Question

Name two plantand animal processes in which diffusion plays an important role

Answer 1

Example of diffusion in plant cells. In order to carry out photosynthesis a plant requires carbon dioxide. On the underside of leaves there are small holes known as stomata, carbon dioxide diffuse into the leaves via these. Leaves produce oxygen and water vapour and these in turn diffuse out via the stomata.

If these were to build up in the cells they would poison them, therefore they diffuse out of the cells into the blood. Replay DIFFUSION IN ANIMAL CELLS Diffusion in animal cells. Another example of diffusion in animal cells is the exchange of carbon dioxide and oxygen between the alveoli in the lungs and the blood.
