Question

Quizplus · Accepted Answer

Plants conserve water by keeping their stomata closed when the weather is hot and dry. Stomata are tiny pores on the leaves of the plants that allow for gas exchange, including the release of water vapor through a process called transpiration. When the stomata are closed, water loss through transpiration is reduced, helping the plant to conserve water.
