Answer Details
Oxygen comes out of the stomata during photosynthesis through the process known as diffusion. Diffusion is a natural process where molecules move from areas of high concentration to areas of low concentration until they are evenly spread out. In photosynthesis, oxygen is produced in the leaves by the plant cells during the light-dependent reactions. The oxygen diffuses out of the plant cell into the surrounding air through the stomata, which are small pores on the surface of the leaf. The stomata open and close to allow for gas exchange, and when they are open, the oxygen can easily diffuse out into the atmosphere. Diffusion does not require energy from the plant and occurs naturally due to the concentration gradient.
