<P> For simple unicellular microorganisms such as the amoeba, one cell division is equivalent to reproduction--an entire new organism is created . On a larger scale, mitotic cell division can create progeny from multicellular organisms, such as plants that grow from cuttings . Mitotic cell division enables sexually reproducing organisms to develop from the one - celled zygote, which itself was produced by meiotic cell division from gametes . After growth, cell division by mitosis allows for continual construction and repair of the organism . The human body experiences about 10 quadrillion cell divisions in a lifetime . </P> <P> The primary concern of cell division is the maintenance of the original cell's genome . Before division can occur, the genomic information that is stored in chromosomes must be replicated, and the duplicated genome must be separated cleanly between cells . A great deal of cellular infrastructure is involved in keeping genomic information consistent between generations . </P> <Table> <Tr> <Td> </Td> <Td> This article relies too much on references to primary sources .
