Question

If a leaf branch of a healthy potted plant is covered a polythene bag tiny water droplets are seen .why does this happen ? Which part of the leaf is responsible ? What are the other function?

Answer 1

When the leaf branch is covered with a polythene bag, tiny water droplets are seen because of transpiration. The leaves lose access amount of water present in the plant through this process. Stomata ( small pores present on the surface) of the leaves are responsible for this.

Answer 2

This happens because when we give extra water to plants, they throw it out in form of water in a process called Transpiration. For this function to happen, stomata ( tiny pores on the surface of leaf) is responsible. This also helps in formation of clouds as they are formed from water vapour.
