What will it happen if stomata would not be there on the leaves?

Dear Niharika,

A stomata is a pore/minute openings, found in the epidermis of leaves, stems, and other parts of plants, that facilitates gaseous exchange. The pore is bordered by a pair of specialized parenchyma cells known as the guard cells that are responsible for regulating the stomatal opening. The main functions of stomata are:

1)They allow gaseous exchange from the surroundings.Usually, carbon dioxide is taken up and oxygen is released during Photosynthesis and oxygen is utilized during the process of Respiration.

2)From stomata, transpiration takes place that is loss of excess water from the aerial parts of the plant. This keeps the plant cool in hot weather.

If stomata is absent in leaves then all these functions will not take place.Photosynthesis, Respiration and Transpiration will not occur.
