How is plant cell cytokinesis different from animal cell cytokinesis?
A) The contractile filaments found in plant cells are structures composed of carbohydrates; the cleavage furrow in animal cells is composed of contractile proteins.
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) Plant cells divide after metaphase but before anaphase; animal cells divide after anaphase.

Question

Quizplus · Accepted Answer

Plant cells deposit vesicles containing cell wall building blocks on the metaphase plate, while animal cells form a cleavage furrow. This is due to the difference in cell wall structure between the two types of cells. Plant cells have a rigid cell wall that must be split in order for cytokinesis to occur. Animal cells, on the other hand, have a flexible cell membrane that can form a cleavage furrow to divide the cytoplasm.
