Question

How did water droplets form inside the plastic bag covering the leaves​

Answer 1

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.

Hope this helps...!

Answer 2

Explanation:

This is because of transpiration from the plant leaves due to sunlight which cannot escape due to the plastic bag and gets condensed and collects inside the bag as water droplets.
