Answer 2

Answer:

The process demonstrates the loss of water that has appeared in the polythene bag is transpiration. As the potted plant covered with polythene bag is kept in the sunlight there will be the loss of water through the stomata present on the leaves. The water drops will appear inside the polythene bag as a result of a loss of water from the stomata. This is due to transpiration.
