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.(4 points)
Mitosis plays a crucial role in healing skin after an injury by producing new cells to replace the damaged ones. During the healing process, the cells near the injured area divide rapidly through mitosis, forming new layers of skin. These cells, known as keratinocytes, divide and differentiate into specialized cells such as epidermal cells, which make up the outer layer of the skin. This process ensures that the new cells are similar in appearance and function to the existing, non-injured skin, allowing for the wound to heal without leaving a noticeable scar.
