WebThe stomata are apertures in the epidermis, each bounded by two guard cells. In Greek, stoma means “mouth,” and the term is often used with reference to the stomatal pore only. Esau (1965, p. 158) uses the term stoma to include the guard cells and the pore between them, and we will use her definition. The plural of stoma is stomata.

WebStomata have two main functions. First is gaseous exchange i.e. intake of carbon dioxide and release of oxygen. The second is the process of transpiration in plants. Air enters the plant through these openings. The carbon dioxide is used in photosynthesis, which also produces oxygen. WebOpening and closure of the stomatal pore is mediated by changes in the turgor pressure of the two guard cells. The turgor pressure of guard cells is controlled by movements of large quantities of ions and sugars into and …
