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 AColumn B
a. Leaf stalki. Transport of minerals
b. Vascular tissuesii. Petiole
c. Stipulesiii. Stomata
d. Guard Cellsiv. Outgrowths
Answer: a-ii, b-i, c-iv, d-iii
