Detailed explanation-1: -Mitosis is the reason we can grow, heal wounds, and replace damaged cells. Mitosis is also important in organisms which reproduce asexually: this is the only way that these cells can reproduce. This is the one key process that sustains populations of asexual organisms.

Detailed explanation-2: -The process of mitosis generates new cells that are genetically identical to each other. Mitosis helps organisms grow in size and repair damaged tissue.

Detailed explanation-3: -Mitosis plays an important role in the production of RBC which assists in wound healing and cell regeneration.

Detailed explanation-4: -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-5: -Mitosis Inhibits DNA Double-Strand Break Repair to Guard Against Telomere Fusions. Science, 2014; DOI: 10.1126/science.
