Correct answer: A. Mitosis
- A. Mitosis
- B. Meiosis
- C. Cell Growth
- D. Mitosis & Meiosis
Explanation
Mitosis is important for three main reasons: development and growth, cell replacement, and asexual reproduction.Mitosis heals wounds by producing new, identical cells through cell division to replace damaged or lost cells, a process called epithelization in the skin. After an injury, the body triggers mitosis, causing cells in the epidermis (outer skin layer) to divide and multiply, migrating to cover the injured area. This increases the cell count, fills in the gaps left by destroyed cells, and reconstructs the damaged tissue, leading to complete or partial repair of the wound.

About Regeneration and Ageing
Regeneration is the replacement of lost or damaged cells, tissues or body parts, ranging from ordinary tissue repair to regrowth in organisms such as planarians. Ageing covers progressive cellular and physiological decline, including reduced repair, senescence, genetic and environmental influences, and the difference between normal ageing and disease.
