As we know that all the living organisms are made up of cells. These cells are developed as a result of a division of pre-existing cells. All the cells are same in chemical composition and metabolic processes. The function of an organism as a whole is the outcome of combined activities and interactions of the constituent cells. The cell is known as the fundamental , structural and functional unit of life.
