Answer 2

Answer:

Place a polythene bag over its one branch as shown in A and tie it with a rubber band. Remove all the leaves from another branch (B) of the same plant, cover this too with a polythene bag and tie it with a rubber band. Place the plant in sunlight, and observe it after 4-6 hours.

Explanation:

Take one small-sized, well-watered potted plant having a few branches. Place a polythene bag over its one branch as shown in A and tie it with a rubber band.

Remove all the leaves from another branch (B) of the same plant, cover this too with a polythene bag and tie it with a rubber band.

Place the plant in sunlight, and observe it after 4-6 hours. You will notice that drops have appeared on the inner surface of the polythene bag over branch A, while no water drops appear on branch B.

This set-up indicates that most water gets evaporated from the plant through its leaves.
