Cytokinesis in animal cells involves: a) Alignment of the spindle along the equatorial plane. b) Formation of a cleavage furrow. c) Pinching in the original cell wall to produce a new cell wall between daughter cells. d) Contraction of a ring of actin microfilaments. e) Development of a cell plate that grows out until it reaches the plasma membrane.

Cytokinesis (cytoplasmic division) in plant cells a. starts when vesicles cluster at the future plane of division. b. occurs when the plasma membrane is pulled inward by a ring of microtubules. c. usually precedes nuclear division. d. involves a cleavage furrow. e. occurs exactly the same as in animal cells.
Which event most accurately describes cytokinesis? A. Cell walls prevent cleavage furrow from deepening. B. Actin molecules are used to develop the cell plate. C. The metaphase plate is the beginning area for cytokinesis. D. Phragmoplast develops in animal cells at the metaphase plate. E. Cytokinesis can begin as early as metaphase.
