In mature animals, cell division is mainly restricted to repair and regeneration of old cells.
Once a being is fully grown, cell reproduction is still necessary to repair or regenerate tissues. For example, new blood and skin cells are constantly being produced. All multicellular organisms use cell division for growth, maintenance, and repair of cells and tissues.
