Question
What is the function of stomata? Which cells open and close the stomata?
Solution
The function of stomata is to allow the exchange of gases between the air and the plant. They are tiny openings or pores, primarily found on the underside of leaves, that take in carbon dioxide and expel oxygen during photosynthesis. They also help in the process of transpiration, which is the loss of water vapor from the plant to the atmosphere.
The opening and closing of stomata are controlled by specialized cells known as guard cells. These cells are shaped like two sausages joined at the ends and they surround each stoma. When the guard cells take in water and swell, the stoma opens. Conversely, when the guard cells lose water and shrink, the stoma closes. This mechanism helps the plant regulate gas exchange and water loss according to its needs and environmental conditions.

What are the functions of stomata and guard cells, and what would happen to a plant if these cells did not function correctly?Group of answer choicesStomata allow gases to enter and exit the plant. Guard cells regulate the opening and closing of stomata. Photosynthesis and, in turn, transpiration, would not occur which is necessary to maintain a continuous flow of water upwards from the roots to the leaves.Guard cells allow carbon dioxide to enter and exit the plant. Stomata regulate the opening and closing of guard cells. Transpiration and in turn, photosynthesis would not occur which is necessary to maintain a continuous flow of water upwards from the roots to the leaves.Stomata allow oxygen to enter and exit the plant. Guard cells regulate the opening and closing of stomata. If the cells didn’t function, photosynthesis would continue but transpiration would cease, which would interfere with the necessary continuous flow of water upward from roots to leaves.Guard cells allow carbon dioxide to enter and exit the plant.
