(d) Tubes called xylem transport water and nutrients to different parts of the plant.
(e) Plants are autotrophic.
(f) The green colour of the leaves is attributed to the colour of chlorophyll.
(g) The chemical needed to test starch is iodine.
(h) Stomata is present under the leaf.
(i) The gas released during photosynthesis is oxygen.
(j) The flat part of a leaf is called the leaf blade.
(k) The stomata remain open during the day in the presence of sunlight.
Question 2: Write True or False:
(a) Carbon dioxide enters into the leaves through chlorophyll – False
(b) Roots are considered as the food factory of the plants – False
(c) During photosynthesis, plants take in carbon dioxide and give out oxygen – True
(d) Photosynthesis takes place even at night – False
(e) The minute openings on the surface of leaves called stomata allows the exchange of gases – True
(f) Plants store excess sugar in the form of glucose – False
(g) The process of making food can be carried on by the plants during the day as well as the night – False
(h) The name of the food prepared by the plants is glucose – True
Question 3: Match the columns:
|Column A||Column B|
|a. Leaves||i. Part from which the baby plant grows and is present in the fruit.|
|b. Fruits||ii. Carry food and water to all other parts.|
|c. Seeds||iii. The part that produce seeds or fruits.|
|d. Flowers||iv. It absorbs water and minerals from the soil.|
|e. Stems||v. Contains seeds.|
|f. Roots||vi. Prepare food for the plant.|
Question 4: Read about chlorophyll and answer the questions:
Chlorophyll is the pigment (colouring agent) present in a plant; however, it is present in abundance in the leaves of the plant. Chlorophyll is responsible for the green colour of the leaves and other parts of the plant body. It is also responsible for absorbing the sunlight required for conducting the photosynthesis process.
(a) You find a plant kept inside the room, over the time it starts drooping down and becomes pale. What should you do to revive the plant?
Answer: We should keep the plant in open area where sunlight is in abundance.
(b) What will happen if you cover the plant with a black paper for one entire day? Give reason for your answer.
Answer: The plant will wilt and become pale as it will be unable to absorb sunlight and thus produce chlorophyll.
(c) Which part of the tree is called food factory? Why is it called so?
Answer: The leaves of the tree are called food factory.
This is because the leaves prepare food for the plant and so, they are called the food factory of the plant.
Question 5: Match the columns:
|Column A||Column B|
|a. Leaf stalk||i. Transport of minerals|
|b. Vascular tissues||ii. Petiole|
|c. Stipules||iii. Stomata|
|d. Guard Cells||iv. Outgrowths|
So, these were Plants Make Food Objective Type Questions & Answers.
