Stomata and guard cells in plants regulate gas exchange, crucial for photosynthesis. If dysfunctional, a plant's gas exchange and photosynthesis processes are impaired.
Stomata are tiny openings found on the surface of plant leaves. They allow for the exchange of gases such as carbon dioxide and oxygen, as well as water vapor.
Guard cells surround each stoma and control its opening and closing. They regulate the passage of gases and water in and out of the plant.
If stomata and guard cells do not function correctly, a plant would have difficulty obtaining carbon dioxide needed for photosynthesis and releasing oxygen produced during this process.
