Transportation in Organisms

Every organism needs to transport various substances within its body. Transportation of substances takes place by osmosis and diffusion in simple organisms, while complex organisms have a well developed system for this. In human beings, there is a well developed blood circulatory system to facilitate transportation of substances. In plants, vascular system is present for the purpose. In complex plants, xylem is responsible for transport of minerals and water; while phloem is responsible for transport of food.
