At night, the stomata close to avoid losing water when photosynthesis is not occurring. During the day, stomata close if the leaves experience a lack of water, such as during a drought. The opening or closing of stomata occur in response to signals from the external environment.
Does the stomata close at night?
Stomata are mouth-like cellular complexes at the epidermis that regulate gas transfer between plants and atmosphere. In leaves, they typically open during the day to favor CO2 diffusion when light is available for photosynthesis, and close at night to limit transpiration and save water.
Which stomata open at night?
Many cacti and other succulent plants with CAM metabolism open their stomata at night and close them during the day.
