Answer:
stomata. Stomata are small openings on the surface of the leaves that allow for gas exchange between the plant and its environment. They are surrounded by specialized cells called guard cells, which regulate their opening and closing. During photosynthesis, the stomata open to allow for the uptake of carbon dioxide from the atmosphere and the release of oxygen as a waste product. At the same time, water vapor is also released through the stomata in a process known as transpiration. The exchange of gases through stomata is crucial for the survival of plants, as it allows them to produce the energy they need to grow and carry out their metabolic processes.
