What is stomata give me the answer

Actually i attended Bilology classes two decades ago. But i still remember that stomata is the outer lining of plants' leaves through which exchange of gas takes place with the surrounding environment.

are tiny openings

Explanation:

Stomata are tiny openings or pores in plant tissue that allow for gas exchange. Stomata are typically found in plant leaves but can also be found in some stems. Specialized cells known as guard cells surround stomata and function to open and close stomatal pores. Stomata allow a plant to take in carbon dioxide, which is needed for photosynthesis. They also help to reduce water loss by closing when conditions are hot or dry. Stomata look like tiny mouths which open and close as they assist in transpiration.

idk and i also need to know where are those bio brainy acts lol
