Detailed explanation-1: -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-2: -When part of a tissue breaks, then there are cells lost. So, mitosis will create tons of new cells in periods of time to fill the gap and make the tissue bigger again. This ensures that the tissue is back to normal and can function properly. It’s like a wound healing.

Detailed explanation-3: -Cells are created through cell division. And mitosis is an important part of this process. Mitosis creates identical copies of cells. For example, it creates new skin cells to replace dead skin cells.

Detailed explanation-4: -Mitosis plays an important role in the production of RBC which assists in wound healing and cell regeneration.
