Process in which one parent cell divides to form two single cells? That process is called Mitosis in regular cells and Meiosis in sex cells or asexual reproduction. Edit
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.
