Understand the definition of mitosis: it is a process of cell division that results in two genetically identical daughter cells from a single parent cell.
Recall that mitosis occurs in somatic cells, which are all the cells forming the body of an organism except the reproductive cells.
Recognize that meiosis is the type of cell division that occurs in germ cells (cells in the gonads) to produce gametes (sperm and egg cells), not mitosis.
Note that bacterial cells do not undergo mitosis; instead, they reproduce by binary fission, a different process.
Conclude that mitosis primarily occurs in somatic (non-reproductive) cells to enable growth, tissue repair, and maintenance.
