Mitosis is the process used during growth to make new cells within a plant or animal. It is also used during asexual reproduction, in which an individual can clone itself to produce identical offspring.
Humans don't make clones of themselves naturally like plants can.
For example: strawberry plants send out runners.
However our body often has to make new cells to replace damaged ones or as we grow. So human cells also go through mitosis in the same way…
