The two main functions of stomata are to allow for the uptake of carbon dioxide and to limit the loss of water due to evaporation. In many plants, stomata remain open during the day and closed at night. Stomata are open during the day because this is when photosynthesis typically occurs. Stomata control gas exchange. When open, these pores allow carbon dioxide in, and oxygen and water out. Carbon dioxide in for carbon fixing. Oxygen out to avoid photorespiration.

Stomata are tiny pores or opening on the surface of a leaf.
Functions of stomata:
(i) Evaporation of water in plants in the form of vapour takes place through stomata during transpiration.
(ii) Exchange of gases (oxygen and carbon dioxide) also takes place through stomata.
