A plant that opens and closes in response to its environment does so through a process called tropism. This is when the plant's cells respond to external stimuli, such as light or touch, by changing their shape or orientation. For example, the opening and closing of a plant's leaves in response to light is known as phototropism. This allows the plant to optimize its exposure to sunlight for photosynthesis.

The function of the guard cells are that they help to regulate the rate of transpiration by opening and closing the stomata thus preventing excessive water loss.
