How is plant cell cytokinesis different from animal cell cytokinesis? a. plant cells divide after metaphase but before anaphase; animal cells divide after anaphase. b. plant cells deposit vesicles containing cell-wall building blocks on the metaphase plate; animal cells form a cleavage furrow. c. the structural proteins of plant cells separate the two cells; in animal cells, a cell membrane separates the two daughter cells. d. the contractile filaments found in plant cells are structures composed of carbohydrates; the cleavage furrow in animal cells is composed of contractile phospholipids?
