In botany, a stoma (plural "stomata ''), also called a stomate (plural "stomates '') (from Greek στόμα, "mouth ''), is a pore, found in the epidermis of leaves, stems, and other organs, that facilitates 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.
