Telanagana State Board Class 6 Science Chapter 9 Plants Parts and Functions Solution:

(1) What are the important parts of a plant?

Ans: – The important parts of a plant are roots, stem and leaves.

(2) How will you tell which part of a plant is the stem and which is the root?

Ans: –The stem of a plant usually have –

(i) Green and Tender stem.

(ii) Hard, woody stem.

(iii) Branches arise from the stem above the surface of the soil.

Generally Roots –

(i) Grow into the soil.

(ii) Some grow deep into the soil and some do not go down much deep.

(iii) These can be taken out of the soil.

(iv) Roots help to fix the plant highly to the soil, and that’s why plant cannot easily uproot.

(v) Roots help in taking up water from the soil.

(3) Collect any plant from your surroundings. Draw its root structure. What can you say about its root system?

Ans: –

I observe the roots of the plants. In this plant, the main root becomes thick and has thin rootlets. This main root is known as top root and the rootlets are called lateral roots.

Observe the roots of this plants, soil is attached to the roots. Roots help to fix the plant tightly to the soil.

So we cannot easily uproot the plant.

We know that root system is help in talking up of water from the soil. The roots do this by absorption. Minerals present in the soil are also absorbed along with the water.

(4) John has no place in his house but he wants to plant vegetables like tomato in his house. Suggest him different ways to do so?

Ans: –

(1) Some fertile soil is taken in a pot or a polythene bag.

(2) Tomato plant is planted in this soil.

(3) This plant with this arrangement is put in the front yard in the house where sunlight falls.

(4) This arrangement also be put on the terrance of the house.

(5) What will happen if a plant doesn’t have any leaves?

Ans: –

(1) Excess of water in the plant is removed in the form of vapours from the leaf surface.

(2) This process is called transpiration and leaves have an important role of activity.

(3) The leaf plays the key role in the preparation of feed for the plant by the process of photosynthesis.

(4) If the plant does not have leaves, the plant cannot perform these important functions.

(5) The plant may not grow and may not give the yield which is supposed to give.

(6) How does the stem help the plant?

Ans: – The stem of a plant bears leaves, buds, flowers, fruits conducts water from the roots to the leaves and to the other parts and food from leaves to roots.

Potato, ginger, onion etc through present in the soil are actually stems and stone food within them.

(7) What type of venation is found in the leaves of plants with fibrous roots?

Ans: –

(1) In a plant with fibrous root, it will not have main root.

(2) Many roots are grown together from the base of the stem.

(3) These do not go down much deep and can be easily separated from the soil.

(4) In the leaves of these plants parallel venation is found.

Parallel venation: –

(1) Plants with fibrous roots have parallel venation in their leaves.

(2) These types of plants have well defined shoot system as well as distinctive body designs.

(3) These roots system are provided with phloem cells.

(8) If the leaves have reticulate venation what would be the type of root?

Ans: –

(1) IF the leaves have reticulate venation, the plant will have one main and long root from which small roots grow.

(2)  The roots go into the soil to more depth.

(3) These root cannot be separated from soil easily.

(9) Explain the various parts of a plant with the help of a diagram?

Ans: – 

 Parts of plants: – A plant is made up of many different parts. The three main parts are: The roots, the leaves and the stem. Each part has a set of jobs to do to keep the plant healthy. The roots absorb water and materials from the soil and anchor the plant in the ground. The stem supports the plant above ground, and carries the water and minerals to the leaves. The leaves collect energy from the sun and make food for the plant using an amazing process called photosynthesis.

(10) Explain the parts of a leaf with the help of a diagram?

Ans: –

Explain:-  Most leaves have two main parts:

(1) The blade and (2) The petiole.

The leaves of some kinds of plants also have a third part called stipules. The blade or lamina is the broad, flat part of the leaf. Photosynthesis occurs in the blade, which has many green food-making cells. It contains a prominent midrib at the center of the leaf blade. From this midrib arise branches called veins.

The petiole: It is the stalk-like structure which connects the leaf blad to the stem. It helps to transport water to the leaf while the other carry food away from the leaf to other parts of the plant.

(11) How can you show that plants absorb water through their roots?

Ans: – We can get this experiment by taking the plant with the roots in a test tube and then filling the test tube wite water upto the stem of the plant. The plant must be near to a plantlet and not some big plant.

Then it can be observed after a certain time the water level will continue to decrease and finally will be depleted/swallowed from the test tube and this proves that the water is absorbed through the roots of the plant.

(12) Rajani said “Respiration takes place in leaves”, is she correct? How can you support this statement?

Ans: – Yes what Rajani is said correct, that Respiration takes place in leaves:

Stomata acts like a nose to the leaf. The exchange of gases in leaves during respiration takes place through stomata. Oxygen from the air enters into a leaf through stomata and reaches all the cells by the process of diffusion. This oxygen is used in respiration in cells of the leaf. The carbon dioxide, produced during diffuses out from the leaf into the air through same stomata.

(14) In Activity 1 your teacher suggested not to harm other plants when you collect plants for observations. Why did she suggest so?

Ans: – She said this because plants give us oxygen and if we harm or kill plants oxygen level will be reduced and because of less oxygen human beings will die.

(16) Observe a plant which has healthy green leaves and beautiful flowers. Write your feelings about the plant in your notebook.

Ans: – The plant looks very beautiful the green leaves and the red flowers make me fresh and attentive. It gives me some positive vibes.

I feel plants are more important that anything without them we can’t live 1 sec also because when they will vanish from earth we will also be vanish. So I think we should plant trees as much as amount.
