Expand the biological significance of mitosis for unicellular and multicellular organisms.

Mitosis is the process of cell division that results in the formation of two daughter cells that are genetically identical to each other and the original cell. It plays a significant role in the life cycle of a wide range of living things, but at different levels.

Mitosis in unicellular organisms such as bacteria enables asexual reproduction by making identical copies of a single cell. In multicellular cells, mitosis plays a role in producing more cells for repair and growth. Therefore, the importance of mitosis in living organisms largely depends on whether the organism is multicellular or unicellular.
