Cytokinesis

OCR AS-level BiologyCell DivisionLesson 10 of 31

Cytokinesis begins during telophase. The cell divides into two daughter cells.

In animal cells a cleavage furrow forms around the middle of the cell. The cell membrane is pulled inwards by the cytoskeleton until it meets in the middle and fuses to form two cells.
