Diffusion occurs in the leaf to facilitate the movement of gases such as carbon dioxide and oxygen. These gases diffuse in and out of the leaf through small openings called stomata, allowing for photosynthesis and respiration processes to take place effectively. This exchange of gases helps the leaf to obtain the necessary substances for energy production and to release waste products.
Faster diffusion will take place if the surroundings are warmer. Increase in temperature means an increase in molecules' speed (kinetic energy).
