Answer» Mostmulticellularplants and animals have too small a surface area to volume ratio so diffusionwouldbe too slow to provide the necessary molecules. Therefore, they require asystemtotransportnutrients and waste products around theorganism. The needs of a plant and animal are similar in some aspects and very different in others. Both need to transport food molecules around the organism but plants, for instance, do not use the transport system to fight disease.
