Question
Describe an experiment to show that the plant loses water through its leaves.
Solution
Experiment: To demonstrate that the plants lose water through its leaves.
- 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
