Why is mitosis responible for for growth, repair, and maintence

Mitosis can be described as a cell division process in which two daughter cells are produced which are identical to one another and to the parent cell. Hence, mitosis is responsible for growth, maintenance and repair because it produces daughter cells which are exact duplicates of the mother cell. For example, damaged skin gets repaired by mitosis as the skin cells duplicate and produce identical copies. Some organisms can even regenerate their entire body parts through the process of mitosis.
