Cytoplasm divides through cytokinesis

Detailed explanation-1: -Cytokinesis begins in anaphase and ends in telophase, reaching completion as the next interphase begins. The first visible change of cytokinesis in an animal cell is the sudden appearance of a pucker, or cleavage furrow, on the cell surface.
Detailed explanation-2: -Cytokinesis is the physical process of cell division, which divides the cytoplasm of a parental cell into two daughter cells.
Detailed explanation-3: -At the final stage of cytokinesis, in a process termed abscission, this bridge is cleaved, and two daughter cells are formed. At the midbody, several cytokinesis-coupled events converge, including degradation of cell cycle regulators, cytoskeleton rearrangements, membrane traffic, and plasma membrane remodeling.
Detailed explanation-4: -Telophase is the fifth and final phase of mitosis, the process that separates the duplicated genetic material carried in the nucleus of a parent cell into two identical daughter cells. Telophase begins once the replicated, paired chromosomes have been separated and pulled to opposite sides, or poles, of the cell.
Detailed explanation-5: -This is also often known as cytoplasmic division or cell cleavage. Cytokinesis begins in anaphase in animal cells and prophase in plant cells, and terminates in telophase in both, to form the two daughter cells produced by mitosis.
