Detailed explanation-1: -The first visible change of cytokinesis in an animal cell is the sudden appearance of a pucker, or cleavage furrow, on the cell surface. The furrow rapidly deepens and spreads around the cell until it completely divides the cell in two.

Detailed explanation-2: -To complete the cell cycle, the cleavage furrow draws the plasma membrane toward the cell center, pinching the cytoplasm into two lobes that are subsequently separated into two cells.

Detailed explanation-3: -Cell division ends with the physical separation of the two daughter cells, a process known as cytokinesis. This final event ensures that nuclear and cytoplasmic contents are accurately partitioned between the two nascent cells.

Detailed explanation-4: -Cytokinesis takes place in four stages: initiation, contraction, membrane insertion and completion. The events occurring within these stages differ in animal and plant cells.
