Answer:
Diffusion is a very important process for photosynthesis where carbon dioxide from the stomata diffuses into the leaves and finally into the cells. Also, during transpiration, the water and oxygen diffuse from the leaves into the environment.
The higher concentration of carbon dioxide in the air around the plant causes the gas to move into the leaf by diffusion. It diffuses through small pores called stomata. The stomata are mainly in the lower epidermis (the underneath surface) of leaves. During photosynthesis, oxygen levels inside the leaf increase. Diffusion is important to cells because it allows them to gain the useful substances they require to obtain energy and grow, and lets them get rid of waste products.
