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?
The answer is B. Due to the presence of a cell wall,
cytokinesis in plant cells is significantly different from that in animal
cells, Rather than forming a contractile ring, plant cells construct a cell
plate in the middle of the cell.
