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..
When Raul scraped his knee, his skin cells were damaged and needed to be replaced. Mitosis, the process of cell division, plays a crucial role in this healing process. Skin cells near the injury site divide rapidly through mitosis to replace the damaged cells. The new cells are identical to the existing, non-injured skin cells because mitosis ensures that the DNA is replicated accurately during cell division. This allows the skin to heal while maintaining the same look and function as before the injury.
