Animal Middle Describe Process Cytokinesis Cells Cytokinesis Cleavage

Animal cell cytokinesis involves a "cleavage furrow" that pinches inward to divide the cytoplasm into two cells.

In animal cells, cytokinesis involves the formation of a cleavage furrow that pinches inwards, eventually dividing the cytoplasm into two cells.

Front Describe the process of cytokinesis in animal cells.
Back Animal cytokinesis:
  • Cleavage furrow forms around middle of the cell
  • Plasma membrane pulled inwards by cytoskeleton until close enoigh to fuse around middle
  • Two cells are formed as a result
