Mitosis is used for growth, repair and asexual reproduction.The size of tissues and organs increases by adding new cells.If the number of cells dying by controlled cell death (apoptosis) is equal to the number of new cells generated by mitosis, the tissue or organ stays the same size.The daughter cells are genetically identical to the parent cell.
