Mitosis

Explanation:

Mitosis is the cell division that forms (two) daughter cells each having the same type and number of chromosomes.

Mitosis is a way of making more cells that are genetically the same as the parent cell. It plays an important part in the development of embryos, and it is important for the growth and development of our bodies as well. Mitosis produces new cells, and replaces cells that are old, lost or damaged.
