The stomata control gas exchanges in each leaf. The open and close as the help aid transpiration. This process is the diffusion of carbon dioxide into the leaf. By allowing the plant to take in carbon dioxide, they are able to photosynthesize. Without carbon dioxide, the plant wouldn't be able to photosynthesize. The stomata also help retain water in the plant by closing when the climate is hot or dry.
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.
