CBSE Case Study Questions Class 6 Science Getting to Know Plants

Case study 1.

Plants can be classified into three categories: herbs, shrubs and trees.Plants with green and tender stemsare called herbs. They are usually shortand may not have many branches. For example- Tomato.Some plants develop branches nearthe base of stem. The stem is hard butnot very thick. Such plants are calledshrubs. For example- lemon. Some plants are very tall and havehard and thick stem. The stems havebranches in the upper part, muchabovethe ground. Such plants are called trees. For example- mango.

Plants with weak stems that cannot stand upright but spread on the ground are called creeper, while those that take support and climb up are called Climber. These are different from the herbs, shrubs and trees.

Que. 1) ………………………………………………..……………………. Is an example of herb?

(c) Pumpkin

Que. 2) Plants that spread on the ground are called Climbers?

Que. 5) Briefly explain with an example, what do you mean by “shrubs?”

Que. 1. b)Tomato

Que. 2. b)False

Que. 3. c)Trees

Que. 4) Answer: Plants with weak stems that cannot stand upright but spread on the ground are called creeper.

Que. 5) Answer: Some plants develop branches near the base of stem. The stem is hard but not very thick. Such plants are called shrubs. For example- lemon.

Case study 2

The stem of a plant helps in upward movement of water. The water and minerals go to leaves and other plant parts attached to the stem.

The part of leaf by which it is attached to the stem is called petiole. The broad, green part of the leaf is called lamina.The lines on the leaf are calledVeins. A prominent line in the middle of theleaf is calledthe midrib. Thedesign made byveins in a leaf iscalled the leaf venation. If this design isNet-like on both sides of midrib, thevenation is reticulate. Inthe leaves of grass you might have seen that the veins are parallel to one another. This is parallel venation.

Que. 1) The middle line of the leaf is called …………………………………………………………………………………..……… .

Que.2) …………………………………………………………………….… is the green part on the leaf?

a) Venation

Que.3) When the veins of Leaves of Grass are parallel to each other. It is called ……………………………………………………………………………………… ?

a) Parallel venation

b) Reticulate venation

d) None of the above

Que. 4) Write the function ofstem in plants?

Que. 5) Explain Reticulate venation in leaves?

Que.1. d)Midrib

Que.2. d)Lamina

Que.3. a)Parallel venation

Que.4) Answer: The stem of a plant helps in upward movement of water. The water and minerals go to leaves and other plant parts attached to the stem.

Que.5) Answer: The design made by veins in a leaf is called the leaf venation. If this design is Net-like on both sides of midrib, the venation is reticulate.

Case study 3

Do this activity during day time on a sunny day. Use a healthy, well-watered plant that has been growing in the sun. Enclose a leafy branch of the plant in apolythene cover and tie up its mouth. Tie up the mouth of another empty polythene cover and keep it also in the sun. After a few hours, observe the inner surface of the covers. You’ll observe droplets of water inside it.Water comes out of leaves in the formof vapour by a process calledtranspiration. Plants release a lot of waterinto the air through this process.

Leaves also have another function, to know that,we would require a leaf, spirit, a beaker, test tube, burner, water, a watch glass and iodine solution for this activity.

Take a leaf in a test tube and pour spirit to completely immerse the leaf. Now, place the test tube in a beaker half filled with water. Heat the beaker till all the green colour from the leaf comes out into the spirit in the test tube. Take out the leaf carefully and wash it in water. Place it on a watch glass and pour some Iodine solution over it. You’ll observe that it has turned blue black, showing the presence of Starch in it.For instance, a slice of raw potato also shows the presence of starch. Potatoes get this starch from their leaves and store it. Leaves prepare their food in the presence of sunlight and a green coloured substance present in them. For this, they also use water and carbon dioxide. This process is called photosynthesis. Oxygen is given out in this process. The food prepared by leaves ultimately gets stored in different parts of plant.

Que.1) Starch is present in the ………………………………………………………………………….……….. of potatoes.

d) Both (b) and (c)

Que.2) Leaves have only one function that is of transpiration.

Que.3) ……………………………………………………………………….…… is given out during the process of photosynthesis?

a) Carbon dioxide

Que.4) Explain the process of transpiration?

Que.5) How do plants prepare food? Mention the process involved?

Que.1. b) Leaves

Que.2. b) False

Que.3. d) Oxygen

Que.4) Answer: Water comes out of leaves in the form of vapour by a process called transpiration. Plants release a lot of water into the air through this process.

Que.5) Answer: Leaves prepare their food in the presence of sunlight and a green coloured substance present in them. For this, they also use water and carbon dioxide. This process is called photosynthesis. Oxygen is given out in this process. The food prepared by leaves ultimately gets stored in different parts of plant.

Case study 4

Roots help in holding the plant firmly to the soil. Theyanchor the plant to the soil. Go to an open ground where many wildPlants are growing. Dig out a few, washthe soil off the roots and observe them.You will find that all of them have eitherthe kind of roots shown in Fig. 1or as in Fig.2. For roots of the kind shown in Fig.1, the main root is called tap root and the smaller roots are called lateral roots. Plants with roots as shown in Fig.2 do not have a main root. All roots seem similar and these are called fibrous roots.

We have learnt that roots absorbwater and minerals from the soil and the stem conducts these to leaves and other parts of the plant. The leaves prepare food. This food travels through the stem and is stored in different parts of plant. We eat some of these as roots— like carrot, radish, sweet potato, turnip and tapioca. We also eat many other parts of a plant where food is stored.

Fig. 1                            Fig. 2

Que.1) Among these plants, whose roots do we eat as vegetables?

c) Sweet potato

d) All of the above

Que.2) A type of roots, having the main root is called ………………………………………………………………………………..……… .

Case study 5

We would require one bud and two fresh flowers each, of any of the following–Datura, china rose, mustard, brinjal,Lady’s finger, gulmohur. Also a blade, aglass slide or a sheet of paper, amagnifying glass and water.Observe carefully and look atthe prominent parts of the open flower. These are the petals. Different flowers have petals of different colours.The partthat is made of small leaf-like structures, are called Sepals. To see the inner parts of the flower clearly, you have to cut it open, if its petals are joined. For example, in datura and other bell-shaped flowers, the petals have to be cut out so that the inner parts can be seen clearly. Remove the sepals and petals to seethe other parts. Study the Fig. 1 and carefully, compare and identify the stamens, anthers and pistil in your flower.The innermost part of flower is called the Pistil.

Let us now study the structure of ovary. It is the lowermost and swollen part of the pistil. We will cut this part to study what is inside! Cut the ovary in two different ways to prevent them from drying, put a drop of water on each of the two pieces of the ovary, you have cut.Observe the inner parts of the ovary using a lens. You will see somesmall bead like structures inside the Ovary. They are called ovules.

The number of sepals, petals, stamens and pistils may also be different in different flowers. Some of these parts may even be absent at times!

Que.1) Dhatura is a flower, having joined petals.

Que.2) Name the inner most part of the flower?

Que.3) The small bead like structures inside the ovary is called ……………………………………………………………………………….……. .

• Jamun (Jamun is a tree while others are herbs).
• Guava (Guava is a tree while others are shrubs).

Question 4. What are climbers and creepers? Give some examples.

Answer: In some plants like grape vines, money plant, bean stalk, gourd plants, etc., the stem is so weak that it cannot hold it straight. They either stand up with some support or they just spread on the ground. In the first condition, the plants are called climbers and in second condition, they are called creepers or runners.

Question 7. Pitcher plant has green leaves which can prepare food by photosynthesis then why does it eat insects?

Answer: Pitcher plant eats insects to get nitrogenous compounds which it neither synthesizes nor can absorb from the soil.

Question 8. What are weeds?

Answer: The unwanted plants that grow in the field with the main crops or in their surroundings are called weeds. Weeds are the plants which are not grown by the farmers, e.g., grass.

Question 9. What is a stem?

Answer: The part of the plant which generally grows above the ground level and bears leaves, flowers and fruits is called a stem.

Question 10. Do you agree that stem is like a two way street?

Answer: Yes. Stem carries the water absorbed by the roots to the leaves and also the food prepared by the leaves to the roots

Question 11. What are the modification of stem?

Answer: Stem is modified to perform certain special functions:

• Storage of food
• Storage of water
• Provide support
• To make food
• Multiplication or reproduction.

Question 12. What are nodes and internodes?

Answer: Nodes: The point where the leaf arises on the stem. They are attached to the stem by a stalk. Internodes: The portion of the stem between the two nodes.

Question 13. Define petiole and lamina.

Answer: The part of leaf which is attached to the stem is called petiole and the broad green part of the leaf is called lamina.

Question 14. What are veins?

Answer: There are some lines on the leaf called veins.

Question 15. What is midrib?

Answer: There is a thick vein in the middle of the leaf called midrib.

Question 16. Why are leaves generally green?

Answer: The green colour of leaves is because of the presence of chlorophyll.

Question 17. What are the modifications seen in a pitcher plant?

Answer: In a pitcher plant, the lamina is modified into a pitcher and apex into its lid.

Question 18. What are lateral roots?

Answer: The smaller roots that grow on the main taproot are called lateral roots.

Question 19. How do you identify the root system of a plant without pulling it out of soil?

Answer: By looking at the venation of the leaves, we can identify the root system of a plants. Plants with leaves having parallel venation have fibrous root and leaves having reticulate venation have taproot.

Question 20. What is a fruit? How does it differ from a seed?

Answer: After fertilization, the ovary of the flower gets stimulated by the action of seed and forms the fruits, like mango, orange, etc. Embryo surrounded by a hard wall is called the seed.

Question 21. Write the functions of sepals and petals.

Answer: Functions of sepals: Sepals protect the inner parts of flower when it is a bud. Function of petals: Petals attract the insects which are the agencies of pollination by colour and fragrance.

Question 22. In what sequence does a plant bear? Seed, Flower, Fruit.

Answer: A plant bears first flowers, then seeds and in the last fruits.

Question 23. Write the names of reproductive parts of a flower.

Answer: The reproductive parts of a flower are:

Question 24. What do you mean by a complete and an incomplete flower?

Answer: The flower with all whorls, i.e., sepals, petals, stamen and carpel in it is a complete flower. If anyone of these is absent in a flower, it is called an incomplete flower.

Long Type Questions and Answers

Question 1. Do all flowers have four separate whorls? Does any flower have more than four whorls? If so, write its name.

Answer: No. Some flowers have some additional whorls than others. Sometimes some of these whorls may even be absent. For example:

• In Gudhal, an additional whorl of epicalyx is found.
• In unisexual flowers, either stamen or pistil is absent.

Question 2. Do all flowers have the same parts and are they arranged in the same way?

Answer: The flowers of different species of plants are different. The number of petals and sepals are different in different flowers. Some of the flowers have stamens and some flowers have only pistil, others have both. Sepals may be connected with petals in some cases; but in other cases, these may be separated. Thus, the properties of flowers are different.

Question 3. Why roots are modified?

Answer: Certain plants have modified roots to perform specific functions:

• Storage roots, e.g., carrot, radish
• Supporting roots, e.g., banyan, rubber
• Climbing roots, e.g., money plant
• Parasitic roots, e.g., dodder
• Breathing roots, e.g., mangroves.

Question 4. Explain the difference between taproots and fibrous roots.

Question 5. What are the main functions of roots?

Answer: Main functions of roots are:

• Roots absorb water and minerals from soil for the other parts of the plants.
• Roots hold the plant firmly to the soil.
• Some roots transform to store food, e.g., radish.
• Roots of leguminous plants contain symbiotic bacteria which add the fertility of soil by fixing atmospheric nitrogen into nitrates.

Question 6. What do you mean by

• leaf venation
• reticulate venation, and
• parallel venation?
• Leaf venation: The design made by veins in a leaf is called leaf venation.
• Reticulate venation: If the design is net-like on both sides of midrib, the venation is called reticulate venation.
• Parallel venation: In the leaves of grass, the veins are parallel to one another. This is called parallel venation.

Question 7. Explain the main functions of leaf.

Answer: There are following two main functions of leaf:

• Transpiration: The extra water comes out of the leaves through stomata in the form of vapour. This process is called transpiration.
• Photosynthesis: The process by which leaves prepare their food from water and carbon dioxide in the presence of sunlight and a green-coloured substance i.e., chlorophyll is called photosynthesis.

Class 6 Science Chapter 4 Case Based Questions - Getting to Know Plants

In a botanical garden, a group of students is observing different types of plants. They come across a plant with a very fragile, long, thin stem that creeps on the ground.

Q1: What type of plant is this? Ans:  This plant is a creeper. Q2: Give examples of two other plants that are considered creepers. Ans:  Two examples of creepers are watermelon and strawberry. Q3: What is the main function of the stem in a creeper? Ans : The main function of the stem in a creeper is to provide support for the plant and carry its weight. Q4: Which of the following is not a characteristic of creepers? (a) Fragile, long, thin stem (b) Grow vertically without support (c) Cannot stand erect (d) Examples include pumpkin and sweet potatoes Ans: (b) Grow vertically without support Q5: How do creepers differ from climbers? Ans Creepers have very thin, long, and fragile stems that creep on the ground and cannot stand erect, while climbers have thin, long stems that use external support to grow vertically and carry their weight. Climbers often have special structures called tendrils to help them climb.

In a garden, there are several plants with bushy and medium-sized structures. The students want to identify the type of plants they are.

Q6: What type of plants are these? Ans: These plants are shrubs. Q7: Give examples of two other shrub plants. Ans: Two examples of shrubs are lemon and henna.

Question 1. How are herbs, shrubs and trees different from each other? Answer: a. Herbs are small non-woody plants with soft stem. These plants are very small in size. These plants usually do not grow more than one metre in height. They have very short life span. These plants do not live for more than two seasons.

b. Shrubs are larger than herbs. These plants are hard and woody. These plants tend to branch near ground level, so many branches are seen rising just above the ground giving them a bushy appearance. Their life span is bigger than herbs but smaller than trees.

c. Trees are fully big plants. They have hard and woody stem. They have a trunk which usually gives out branches and leaves. The branches appear higher up on the stem much above the ground. Trees have a great life-span. They live for many years.

Question 2. What is leaf venation? Explain the various types of leaf venation with an example for each. Answer: The design made by veins in a leaf is called leaf venation. The leaf venation have two main types: a. Reticulate venation: In this type of venation, the veins occur in an irregular way forming a net-like design. Pea plant, neem tree, mango tree, marigold, etc., have reticulate venation, b. Parallel venation: In this venation, the veins in a leaf run parallel to one another on both the sides of the midrib. Wheat, paddy, sugarcane, barley, etc., have parallel venation.

Question 3. What are roots? Write the various functions of roots. Describe the two types of roots. Answer: Roots are the parts of plants which grow below the ground (in the soil). Various functions of roots are:

• Roots prevent the plant from being pulled out easily or blown away by the wind.
• Roots absorb water and minerals from the soil for manufacturing of food.
• Roots help in conservation of soil by holding it together.

The two main types of roots are: Taproot and Fibrous root

• Taproot is the main root from which many branching roots grow sideways. Pea plant, radish, mango, mustard, etc., have taproot.
• Fibrous root is a cluster of thin fibre like roots at the base of the stem. These roots spread out in the plants. Wheat, maize, grass, millet, etc., have fibrous roots.

Question 4. Explain the structure of a leaf. What are the main functions of a leaf? Answer: The main parts of a leaf are:

• Petiole: The part of the leaf by which it is attached to the stem is called petiole.
• Lamina: The broad, green part of the leaf is lamina.
• Veins: There are various types of lines on the leaf which are called veins.
• Midrib: There is a thick vein in the middle of the leaf. This vein is called midrib.

There are following two main functions of a leaf:

• Transpiration: In the form of vapour, extra water comes out of the leaves. This process is called transpiration. It helps in cooling and absorbing water from soil by the roots.
• Photosynthesis: The process, by which leaves prepare their food from water and carbon dioxide, in the presence of sunlight and chlorophyll is called photosynthesis.

Question 5. Explain how flower becomes a fruit. Answer: When the pollen grains fall on stigma, they move down through the tube called style and reach the ovary. In the ovary, the male sex cells present in pollens join with the female sex cells present in ovules. The joining together of male and female sex cells is called fertilization. After fertilization, the ovules grow and become seeds. The ovary of flower grows and becomes a fruit.

Question 3:

Can you find a plant in your house or in your neighbourhood which has a long but a weak stem? Write its name. In which category would you classify it?

The money plant has a long and weak stem. It comes under the category of climbers. Climbers are plants that readily take support on neighbouring structures as they have a weak stem.

Question 4:

What is the function of a stem?

The main function of a stem in plants is that it helps in the conduction of water and minerals from the roots to the leaves and other parts of plants. It also provides support to branches, leaves, flowers, fruits, and buds of plants.

Question 5:

Which of the following leaves have reticulate venation?

Wheat, tulsi , maize, grass, coriander ( dhania ), China rose

The leaves of tulsi , coriander, and China rose have reticulate venation, whereas maize, grass, and wheat have parallel venation.

In leaves with reticulate venation, the veins are arranged in a net-like pattern. In parallel venation, the veins are arranged parallel to one another.

Leaves with reticulate and parallel venation

Question 6:

If a plant has fibrous roots, what type of venation do its leaves have?

Plants with fibrous roots have parallel venation in their leaves. For example, grass, wheat, maize, etc. have fibrous roots with parallel venation.

Fibrous roots with parallel venation

Fibrous roots have thin and moderately growing branches arising from the stem. Parallel venation, on the other hand, has leaves in which the veins are arranged parallel to each other.

Question 7:

If a plant has leaves with reticulate venation, then what kind of roots does it have?

Plants with reticulate venation in their leaves are likely to have tap roots. For example, a carrot or a rose plant has leaves with reticulate venation and its roots are called tap roots.

Taproots and reticulate venation

In tap roots, there is one main root known as the ‘tap root’ that grows straight down from the stem. It also has smaller roots known as ‘lateral roots’. In leaves with reticulate venation, the veins are arranged in a net-like pattern.

Question 8:

Is it possible for you to find out whether a plant has taproot or fibrous roots by looking at the impression of its leaf on a sheet of paper?

Yes, we can recognize the roots of a plant by looking at the leaves. You can look for the type of roots of the plant and identify the type of leaf. If the plant has fibrous roots, then its leaves have parallel venation, and if the plant has tap roots, then its leaves have reticulate venation.

Question 9:

What are the parts of a flower.

A flower consists of sepals, petals, stamens, and pistils. A stamen has two parts called the anther and the filament. A pistil has three parts called the stigma, style, and ovary.

Getting to Know Plants Class 6 Notes - Chapter 7

According to the CBSE Syllabus 2023-24, this chapter has been renumbered as Chapter 4.

In our garden, we have seen different varieties of plants. Few are tiny grasses, bushes, flowering plants and tall coconut trees. But how are these plants classified?

Let us learn in detail about the plants and their classifications.

Introduction

Introduction to plants.

Plants are all around us. They help sustain life on earth by creating food and giving out oxygen that we breathe in.

• Plants are the immovable living organisms all around us.
• They are the primary food providers.
• They are mostly green in colour and use the sun as a source of energy to make food.

Herbs, shrubs and trees

• Herbs are the smallest plants and do not have woody stems.
• Shrubs are slightly larger than herbs.
• Trees are the largest plants and can have large and thick woody stems.

For more information on Types of Plants, watch the below video

Creepers and Climbers

Creepers and Climbers are types of plants which need support to grow.

Algae and Mosses

• Algae and mosses are the most primitive or simple plants.
• Algae are found mostly floating on water, and mosses are seen on surfaces, rocks or bark of trees in humid conditions.

The leaf is the most important part of the plant. Most leaves of plants are green in colour. There are different shapes and sizes of leaves.

Different Parts of a Leaf

Leaf has different parts:

• the leaf blade/lamina

Transpiration

Transpiration is the loss of water from aerial parts of the plant, especially from leaves. Water is lost in the form of water vapours through tiny openings called stomata, present on the underside of leaves.

Photosynthesis

Photosynthesis is the process by which the plant converts carbon dioxide and water into food using sunlight as the energy source. Photosynthesis happens in green leaves.

The root is the part of the plant that is found under the soil. It provides stability to the plant and also absorbs water and minerals.

Types of Roots

There are two types of roots; tap root and fibrous root. Tap roots are seen in large trees and shrubs. Fibrous roots are common in herbs.

Relation Between Different Types of Leaves and Roots

Leaf venation and the type of roots in a plant are related. Plants with fibrous roots have parallel venation in their leaves. Plants with tap roots have reticulate venation in their leaves.

Stem is the main part of the plant. It gives structural support and helps in transportation of the water, minerals and food. The leaves and branches originate from the stem.

A flower is the reproductive part of a flowering plant. The only function a flower serves is reproduction. Different parts of a flower have different functions.

Different Parts of Flowers and Their Function

The flower is made up of four important parts. The sepals, the petals, the male stigma and the female style.

Reproduction in Flowering Plants

Reproduction in flowers happens when the pollen grain from the male androecium fuses with the eggs in the female style.

A seed is an enclosed dormant embryo of a plant. They are found in the fruits and, when sown, give rise to a new plant.

Parts of a seed

A seed is made up of different parts. The plumule gives rise to the shoot, and the radicle grows into the roots. The cotyledons provide nutrition.

Types of seeds

There are two types of seeds on the basis of the number of cotyledons. Monocots have single cotyledon. Dicots have two cotyledons.

Food: Fruits and Vegetables

• Fruits are very different from vegetables.
• Fruits always develop from a flower, while vegetables are parts of the plant that are edible for us. It could be the shoots, the leaves, the roots or even the fruits.
• Tomato is a classic example of a vegetable as a fruit too.

FAQs on CBSE Class 6 Science Getting to Know Plants Worksheets

Plants can be classified into three different categories based on their characteristics. These different types of plants are named Herbs, Shrubs and Trees. Herbs are plants with tender and green stems that can be easily bent. They are usually short in height and have only a few branches. Shrubs are relatively taller plants compared to herbs. They have but not very thick stems and they branch out near the base of the plants. Trees on the other hand are very tall and have thick and hard stems that are called trunks. In trees, stems have branches in the upper part.

Chapter 7 Getting to Know Plants in class 6 NCERT Science textbook helps students get an in-depth understanding about plants, different classifications of plants, parts of a plant etc. By the end of the lesson, students will be able to identify different types of plants, list the parts of a plant, identify different types of roots, list the various functions of roots and understand the structure and function of a stem. The chapter also aims to make the students understand the different parts of a flower.

A plant consists of different parts such as stems, leaves, roots and flowers. The stem is the part of plants that holds the plant upright and carries water, minerals and food to different parts. The leaves of the plant function as the kitchen of the plant where food is prepared by the process of photosynthesis. The flower is the reproductive part of a plant and roots are the non-green part of a plant body that is usually found underground and helps in absorbing water and minerals from the soil.

Stems are considered one of the most important parts of a plant and it belongs to the shoot system. The stem is assigned with the function to hold the plant upright and bear leaves, flowers and fruits. They also have a very significant function of carrying the water and minerals that are absorbed from the soil to the rest of the plant through tubes called xylem and also carrying the food prepared by the leaves to the different parts through another set of tubes called phloem.

Long Answer Type Questions

1. What do you mean by leaf venation? Explain various types of leaf venation with example.

Answer: Leaf venation: The design made by veins in a leaf is called leaf venation. There are the following two types of leaf venation:

(i) Reticulate venation: If the design of veins makes a net-like structure on both the sides of midrib then it is called reticulate venation. For example, mango leaf, gram leaf.

(ii) Parallel venation: If the veins are parallel to each other or to midrib then such type of venation is called parallel venation. For example, wheat leaf, barley leaf.

2. Explain the structure of a typical flower.

Answer: A typical flower contains the following parts: Stalk:  The part by which a flower is attached to the branch is called stalk. Sepals:  The small green leaf-like structures of the flower are called sepals, Petals:  The big coloured leaf-like structures are called petals. Different flowers have petals of different colours. Stamen:  It is the male part of the flower. It has two parts: (a) Filament and (b) Anther. Pistil:  The innermost part of a flower is called pistil. It has three parts: (a) Stigma, (b) Style and (c) Ovary. It is the female part of the flower.

3. Explain an activity to test the presence of starch in a leaf.

Answer: Take a leaf in a test tube and pour spirit till it completely covers the leaf. Now put the test tube in a beaker having water. Heat the beaker till all the green colour from the leaf comes out into the spirit in the test tube. Take out the leaf and wash it with water. Put it on a plate and pour some iodine solution over it. The iodine solution is brown in colour but when it comes in contact with starch it turns blue-black. The iodine solution will turn blue-black when dropped on the leaf, this confirms the presence of starch in the leaf.

4. Explain that sunlight is essential for photosynthesis.

Answer: Take a potted plant having green leaves. Place it in a dark room for a day or two so that all the starch present in leaves is used by the plant. Now cover a portion of leaf with black paper and keep the plant in the sun for a day. Pluck the leaf, remove the black paper and test it for the starch. We see that only that part of the leaf becomes blue-black which was open to sun. The covered part does not become blue-black. This shows that no starch is formed because it gets no sunlight.

5. Explain the important functions of root.

Answer: The following are the functions of root: (i) They help to absorb water from the soil. (ii) The roots help in holding the plants firmly in the soil. (iii) They are said to anchor the plant to the soil.

6. Explain various kinds of roots with the help of an example.

Answer: There are following two types of roots: (i)  Tap roots:  The roots which have one main root and other smaller lateral roots are called tap roots. For example, mustard plant, gram. (ii)  Fibrous roots:  The roots which have no main root but all the roots appear similar are called fibrous roots. For example, maize, wheat.

Answer: There are two main parts of leaf: (i)  Petiole:  The part of the leaf by which it is attached to the stem is called petiole. (ii)  Lamina : The broad, green part of the leaf is called lamina.

The lamina contains following parts: (i)  Veins:  There are various types of lines on the leaf. These lines are called veins (ii)  Midrib:  There is a thick vein in the middle of the leaf. This vein is called midrib.

10. Explain the main functions of leaf.

Answer: There are following two main functions of leaf: (i)  Transpiration:  The extra water comes out of the leaves in the form of vapour. This process is called transpiration. (ii)  Photosynthesis:  The process by which leaves prepare their food from water and carbon dioxide, in the presence of sunlight and a green-coloured substance, is called photosynthesis.
