The timing of the cytoplasm splitting can differ, and in some cases, the cytokinesis machinery is modified or delayed. Animal Cytokinesis One of the most notable differences lies between plant and animal cells.

However, the timing and specific regulation of these events are tailored to the unique requirements of reducing the chromosome number. Unlike the typical division seen in somatic cells, this process reduces the chromosome number by half, creating four unique haploid cells from a single diploid parent.
By this point, the cells are haploid, and the sister chromatids have separated during anaphase II. The mechanism is generally similar to mitosis, involving the formation of a contractile ring of actin and myosin filaments that constricts the cell membrane.

Cytokinesis I: The Reductional Division The first act of cytokinesis occurs immediately following anaphase I of meiosis I. Plant cells, however, cannot flex their rigid cell walls, so they construct a cell plate from the inside out.
