Mitosis is immediately followed by [[cytokinesis]], which divides the nuclei, [[cytoplasm]], [[organelle]]s and [[cell membrane]] into two cells containing roughly equal shares of these cellular components. Cytokinesis occurs differently in plant and animal cells. While the cell membrane forms a groove that gradually deepens to separate the cytoplasm in animal cells, a [[cell plate]] is formed to separate it in plant cells. The position of the cell plate is determined by the position of a preprophase band of microtubules and [[actin]] filaments. Mitosis and cytokinesis together define the [[cell division|division]] of the parent cell into two daughter cells, genetically identical to each other and to their parent cell. This accounts for approximately 10% of the cell cycle.

Because cytokinesis usually occurs in conjunction with mitosis, "mitosis" is often used interchangeably with "M phase". However, there are many cells where mitosis and cytokinesis occur separately, forming single cells with multiple nuclei in a process called [[endoreplication]]. This occurs most notably among the [[fungus|fungi]] and [[slime mold]]s, but is found in various groups. Even in animals, cytokinesis and mitosis may occur independently, for instance during certain stages of [[Drosophila melanogaster|fruit fly]] embryonic development.<ref name=Lilly>{{cite journal | vauthors = Lilly MA, Duronio RJ | title = New insights into cell cycle control from the Drosophila endocycle | journal = Oncogene | volume = 24 | issue = 17 | pages = 2765–2775 | date = April 2005 | pmid = 15838513 | doi = 10.1038/sj.onc.1208610 | s2cid = 25473573 | doi-access =  }}</ref> Errors in mitosis can result in cell death through [[apoptosis]] or cause [[mutation]]s that may lead to [[cancer]].
