None. Leaves "breathe" in Carbon Dioxide, and put out Oxygen.
A leaf takes in sunlight and carbon dioxide.
Carbon dioxide enters a leaf through small openings called stomata on the surface of the leaf. The stomata open to allow carbon dioxide to diffuse into the leaf from the surrounding air. Once inside the leaf, carbon dioxide is used during photosynthesis to make glucose and oxygen.
For photosynthesis to occur in a leaf, three key substances need to be present: sunlight, water, and carbon dioxide. Sunlight provides the energy needed for the process, water is absorbed from the soil and transported to the leaf through the plant's vascular system, and carbon dioxide is taken in from the air through tiny pores called stomata on the leaf surface.
through the pores in the stomata of the leaf
the leaf!
Carbon dioxide uses stomata as its route into the leaf for photosynthesis. Stomata are small pores on the leaf surface that allow gas exchange, with carbon dioxide entering the leaf through these openings during photosynthesis.
the leaf has super little holes. The holes breathe in the carbon dioxide.
carbon dioxide im doing a project now
by the leaf
it has no choice but to
it gets it by going through the guard cells and stoma
Carbon dioxide leaves a leaf through small openings called stomata on the surface of the leaf. The concentration of carbon dioxide inside the leaf is higher than in the atmosphere, causing it to diffuse out of the leaf through the stomata.
