Detailed explanation-1: -Mitosis is crucial to this process. Mitosis is the reason we can grow, heal wounds, and replace damaged cells.

Detailed explanation-2: -When the cells undergo oriented mitotic division to repair the wound by natural process, the impaired skin can complete perfect repair; and when the cell division orientation is random, there will form fibre hyperplasia, abnormal tissue structure and eventually lead to scar formation.

Detailed explanation-3: -An essential purpose of mitosis is to replace dead or damaged cells like skin cells that are constantly being shed. Mitosis also gets to work when the body experiences a cut or a broken bone. Mitosis quickly replaces lost cells to restore normal functioning.

Detailed explanation-4: -Mitosis helps in the production of identical copies of cells and thus helps in repairing the damaged tissue or replacing the worn-out cells. But the degree of regeneration and replacement in multicellular organisms vary from one another.
