Different types of cells and tissues are present because organisms perform many specialised functions. Cells become structurally modified for particular tasks like protection, transport, support, movement and coordination, improving efficiency through division of labour in multicellular organisms.

Different cells and tissues exist because living organisms perform various complex activities. Through differentiation, cells develop specialised structures suited for specific functions such as transport, support, protection, movement and coordination. This specialisation creates division of labour among tissues and organs. As a result, body functions become more organised, efficient and coordinated in multicellular plants and animals.
