WebWe know that in higher green plants, some substances enter the living cells through the aerial organs—the diffusion of CO 2 and O 2 from the atmosphere into the plants is principally through stomata. From soil, water and ions of simple inorganic salts pass into the plants through the root cells by a process which is basically diffusion, though greatly … WebDiffusion in Multicellular Organisms. Large, multicellular organisms like humans have relatively small surface areas ( SA) in comparison to their volumes (in comparison to single-celled organisms) This means that the distance between the surface of the organism to its centre is relatively large. This is why larger organisms usually have ...
