Guard cells use osmotic pressure to open and close stomata, allowing plants to regulate the amount of water and solutes within them. How do stomata know when to close? The opening and closing of stomata is governed by increases or decreases of solutes in the guard cells, which cause them to take up or lose water, respectively. In general, stomata open by day and close at night. During the day, stomata close if the leaves experience a lack of water, such as during a drought. When the guard cells become turgid, they expand, causing stomata to open. WebAnswer (1 of 3): In most but not all plant species stomata are open during the day and closed during the night. In order for plants to produce energy and maintain cellular function, their cells undergo the highly intricate process of photosynthesis . The opening and closing of stomata happen by two contrasting mechanisms described below: What controls the opening and closing of stomata? Structure of stomata Stomata are composed of two guard cells. They control water loss and gas exchange by opening and closing. WebIn leaves, they typically open during the day to favor CO 2 diffusion when light is available for photosynthesis, and close at night to limit transpiration and save water. When osmotic pressure decreases, water moves out and makes the stomata close due to which stomata become more flaccid. This makes the inner thick walls to come near each other so the stomata close. When water moves into guard cells from surrounding cells, they become turgid and bend, producing a pore. They control water loss and gas exchange by opening and closing. These cells have walls that are thicker on the inner side than on the outer side. Stomate, also called stoma, plural stomata or stomas, any of the microscopic openings or pores in the epidermis of leaves and young stems.
