Stomata are composed of a pair of specialized cells that are found on the leaves of many plants. Stomata open and close for gas exchange & water regulation.

Which explanation best describes one of the relationships between stomata & plants maintaining homeostasis?

• Stomata help regulate the internal temperature of plants.

• Stomata help regulate the glucose level of plants.

• Stomata help to exchange oxygen and carbon dioxide for plants.
