stoma or stomate or stomata or stomates

Microscopic openings in plant tissues, usually in leaves (usually undersides) and stems, allowing for gaseous exchange and transpiration of water. Carbon dioxide enters the tissue through these pores, and water vapor is lost to cool the leaf. They occur between two adjoining specialized cells, called guard cells. Variation in the guard cell size by turgor adjusts the size of the opening. When pressure is low, the stomata are small to reduce loss of water, but they become larger when photosynthesis increases.
