| Tanmay took a potted, well watered plant and set-up an experiment as shown in figure. |
|
| Then, he put it in the sunlight for few hours. Which of the following options is correct regarding his observation? |
A) Water droplets are visible in polythene X as transpiration takes place through leaves.
B) Water droplets are visible in polythene Y as transpiration takes place through stems.
C) Water droplets are visible in polythene X as photosynthesis occurs in leaves.
D) Water droplets are visible in polythene Vas photosynthesis occurs in stem.
Correct Answer: A
Solution :
Most of the transpiration takes place through leaves which results in loss of water in the form of water vapours from the plants through stomata. Since in polythene X leaves are covered, water vapours released in the atmosphere will get collect in the polythene, and are thus, visible in the form of water drops. Polythene Y has no leaves inside it, therefore, no water droplets are visible in it.
