WebPlants in moist environments would require more stomata. This is because “Plants move water from soils to leaves through a passive evapotranspiration process which provides more hydrogen ions for photosynthesis.” (Boyer, 2015). Therefore, water movement is completely reliant on stomata density and water availability. 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.
