Answer:
Stomata are the small pores in leaves of plants. They act as lungs. Stomata take in carbon dioxide and give out oxygen during photosynthesis and visa versa during respiration, thus enabling the exchange of gasses.

Answer:
In botany, a stoma, also called a stomate is a pore, found in the epidermis of leaves, stems, and other organs, that controls the rate of gas exchange. The pore is bordered by a pair of specialized parenchyma cells known as guard cells that are responsible for regulating the size of the stomatal opening.
