WebThe opening and closing of stomata depend on the turgor pressure, caused by the osmotic flow of water in the guard cells. When the guard cells are turgid, they expand resulting in the opening of stomata. When the guard … 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.

WebThe stomata open and close according to the physiological needs of the leaf. In hot and arid climates the stomata may close to conserve water, but this closure limits the entry of carbon dioxide and hence the rate of photosynthesis. The decreased transpiration means there is less cooling of the leaves and hence leaf temperatures rise. The ...
