It is defined as the division or cleavage of cytoplasmic part of the cells into two daughter cells. It is first indicated during late anaphase by appearance of an annular, indentation or cleavage furrow upon cell surface at the level of equatorial plane of spindle ( same as previously occupied by metaphase plate.) The furrow progress ively deepens like a contractile ring and ultimately splits the cells into daughter cells at about the end of telohase. Cytoplasmic microfilaments , including those of myosin and actin appear to be involved information of the furrow and its progressive contraction . plants cells do not divide by furrowing , but by formation of a cells plate in the plane of meta phase plate,
Before final cell cleavage, the main cytoplasmic organelles , except golgi complex, segregate in polar regions of the parent cells so that they may be almost equally distribution to the resultant daughter cells.
