The cytoplasm divides during telophase, the last phase of mitosis. Alter the cytoplasm divides, two daughter cells are produced from the parent with identical nuclei.
Most of the process of cytokinesis in animal cells occurs during telophase, although it begins in the nuclear division phase called anaphase. The cytokinesis process occurs when the cell membrane pinches between the two daughter nuclei; this in turn creates two daughter cells. This last step occurs when a ring of protein filaments, known as the contractile ring, pinches the membrane inward, separating the cells. In plant cells, a cell wall grows between the daughter nuclei to form two different cells. Cytokinesis sometimes creates two cells that are not identical, such as if one cell receives more of one type of organelle than the other.
