Cytokinesis starts in early stages of mitosis, anaphase and ends in telophase. The process is dependent on karyokinesis. Now the main difference between cytokinesis in plant and animal cell is, plant cells have a cell wall that needs to be split while animals do not have any cell wall. While this is the last event of cell division, it starts early on during the anaphase stage of mitosis in most eukaryotic cells. Cytokinesis generally involves the extensive restructuring of the cellular contents, and it begins after the chromosomal segregation. The separation of one cell into two is accomplished by a structure called the contractile ring. Once the daughter cells are separated, cellulose synthesis begins, and the cell plate becomes a primary cell wall. Dec 06, 2018 · The process of cytokinesis is defined as the division of the cytoplasm to form two different daughter cells after the process of mitosis has taken place.
