Gas enters leaves primarily through tiny openings called stomata, which are located on the leaf's surface. These stomata can open and close to regulate gas exchange, allowing carbon dioxide to enter for photosynthesis while enabling the release of oxygen and water vapor. The process is facilitated by the diffusion of gases, driven by concentration gradients between the inside of the leaf and the surrounding air. Additionally, the leaf's internal structure, including air spaces in the mesophyll, aids in efficient gas exchange.
