chromosome condensation

an animal cell in the process of cytokinesis

an animal cell in anaphase of mitosis

a plant cell in the process of cytokinesis

a plant cell in metaphase of mitosis

telophase

anaphase

prophase

metaphase

The contractile filaments found in plant cells are structures composed of carbohydrates; the cleavage furrow in animal cells is composed of contractile proteins.

Plant cells deposit vesicles containing cell wall building blocks on the metaphase plate; animal cells form a cleavage furrow.

The structural proteins of plant cells separate the two cells; in animal cells, a cell membrane separates the two daughter cells.

Plant cells divide after metaphase but before anaphase; animal cells divide after anaphase.

The cell underwent repeated cytokinesis but not mitosis.

The cell underwent repeated mitosis with simultaneous cytokinesis.

The cell underwent repeated mitosis, but cytokinesis did not occur.

The cell had multiple S phases before it entered mitosis.
