The correct answers is : They allow the exchange of gases between cells in the leaf and the external environment
The stomata are small openings that can be found on both the upper and the down part of the leaf and they are connected to the plant's vascular system.
These openings enable the plant to get rid of excess water in the form of vapor and to take CO2 from the atmosphere that is essential for the process of photosynthesis.

During photosynthesis, the stomata allow the exchange of gases between cells in the leaf and the external environment.
What are stomata in plants?
Stomata are openings found on the leaves of plants which play essential roles in gaseous exchange and in transpiration in plants.
During the process of photosynthesis, the stomata play important roles in gaseous exchange between the plant and the environment, allowing carbon dioxide to move in and oxygen to move out of the plant.
Therefore, the stomata allow the exchange of gases between cells in the leaf and the external environment.
