Mitosis

Explanation:

Mitosis is the process of cell division. In this process cells are split to create exact replicas of eachother. It is why we don't grow ears on our hands when they are injured. The hand cells are replicated to create more, so it heals correctly. In the Mitosis the two resulting daughter cells always have the same number of chromosomes from the parent cell. Their role is to maintain the same number of chromosomes in each cell division constant, which allows us to grow and self-maintain our bodies.
