Responses of stomata to the environment

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.

The loss of water in the guard cells causes them to shrink. This shrinkage closes the stomatal pore. When conditions change such that stomata need to open, potassium ions are actively pumped back into the guard cells from the surrounding cells.
