Raul has scraped his knee and noticed that after a week it had almost completely healed. Raul wondered how the skin was able to repair itself while looking exactly the same as his non-injured skin. In 3-5 sentences explain how mitosis plays a role in healing skin after injury and is able to maintain the look of the existing, non-injured skin.
Mitosis plays a vital role in the healing process of the skin after injury. During mitosis, skin cells divide and multiply, forming new cells to replace the damaged ones. As these new cells are produced, they migrate to the site of injury, filling in the wound and promoting skin regeneration. Mitosis ensures that the new cells are genetically identical to the existing, non-injured cells, allowing the healed skin to have the same appearance as the surrounding skin. This process allows for the seamless integration of new cells, resulting in the healing of the skin without any visible scarring or differences in texture or color.
