What roles do the stomata in a plant's leaves play in photosynthesis?

• Stomata are found only on the upper surface of leaves.

• Stomata open during the night and close during the day.

• Stomata are responsible for the exchange of gases, such as oxygen and carbon dioxide.

• Stomata do not play a role in regulating water loss in plants.
