<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>
