WebThe opening and closing of stomata, which are small openings on the surface of leaves and stems of plants, is regulated by the movement of ions and water across the guard cells that surround the stomata. When the concentration of K+ ions increases in the guard cells, water moves into the cells, causing them to swell and the stomata to open. 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 … WebThe stomata is the turgor operated valve in the epidermis. The opening and closing of the stomata are controlled by the size and shape of the guard cells which have differential wall thickening and turegidity.
