Quizplus · Accepted Answer

Stomata are small pores on plants that open to allow gas exchange, such as oxygen and carbon dioxide, to enter and exit the plant. However, they also allow water to escape through transpiration. Therefore, stomata close to decrease water loss and prevent dehydration in the plant. While stomata do occur in most land plants, they are not the defining characteristic of the group and are not the same as pores. Stomata do not open to increase water absorption, as their main function is gas exchange.
