Excretion is the process of eliminating waste products of metabolism and other non-useful materials.It is an essential process in all forms of life. It contrasts secretion, where the substance may have specific tasks after leaving the cell.
In single celled organisms, waste products are discharged directly through the surface of the cell. Multi-cellular utilize more complex excretory methods. Higher plants eliminate gases through the stomata or pores, on the surface of leaves. Animals have special excretory organs.
