Understand the definition of mitosis: it is a type of cell division that results in two daughter cells each having the same number and kind of chromosomes as the parent nucleus, typical of ordinary tissue growth.
Recall that mitosis primarily occurs in somatic cells, which are all the non-reproductive cells in a multicellular organism.
Recognize that gametes (sperm and egg cells) are formed by meiosis, not mitosis, because meiosis reduces the chromosome number by half to maintain genetic stability across generations.
Note that prokaryotic cells do not undergo mitosis; instead, they divide by a simpler process called binary fission.
Understand that haploid cells undergoing synapsis and crossing over are involved in meiosis, not mitosis, as these processes are specific to the formation of gametes.
