Understand the definition of mitosis: it is a process of cell division that results in two genetically identical daughter cells, maintaining the same chromosome number as the original cell.
Recall that mitosis primarily occurs in somatic (body) cells, which are all the cells forming the tissues and organs of the body except for the reproductive cells.
Recognize that haploid gametes (sperm and egg cells) are produced by meiosis, not mitosis, and thus mitosis does not occur in these cells.
Note that prokaryotic cells do not undergo mitosis; instead, they reproduce by binary fission, a different process of cell division.
Understand that cells undergoing meiosis I in the gonads are involved in producing gametes and do not undergo mitosis during this stage.
