Definitions for "Stomata"
tiny openings in the epidermis of plants, surrounded by a pair of guard cells that can close off the opening by changing shape
The pore openings underneath plant leaves that can open and close according to the metabolic needs of the plant. They are the ports for exchange of oxygen and carbon dioxide gas for photosynthesis, but also release excess water into the air. This process of water loss maintains a steady flow of water and minerals from the roots to the leaves. To minimize the water loss, many plants regulate the duration and time of day when stomatas are open.
