Explain why the rate of diffusion of carbon dioxide into stomata on a leaf is higher on a warm day

An increase in temperature increases the rate of evaporation and decreases the relative humidity of the environment. The more stomata on the leaf, the more water evaporates the leaf.

In addition to lowering carbon dioxide levels during photosynthesis, light can have a direct effect on guard cells, causing them to swell.

sorry to break it to ya but no one can answer your question it's just

jk but i am serious about the part that most people cant answer it beacuse you did not mention the section you are talking about. but it would if you added some detail and were a bit more specific.
