Which statement about plant cytokinesis is true? A) It begins after telophase ends. B) A division furrow completely separates the cytoplasm. C) It is under the control of Ca²⁺. D) Vesicles fuse to form a cell plate. E) The spindle fibers break down to form a cell plate.

Question

Quizplus · Accepted Answer

Plant cytokinesis involves the formation of a cell plate, which is derived from vesicles that fuse together to form a new cell wall. This is distinct from animal cytokinesis, which involves the formation of a cleavage furrow that completely separates the two daughter cells. The process of cytokinesis begins after telophase, when the nuclear envelope reforms around the two sets of chromosomes. Plant cytokinesis is regulated by a variety of proteins and signaling molecules, but Ca²⁺ is not a known player in this process. Lastly, while the spindle fibers do break down during cytokinesis, they do not directly contribute to the formation of the cell plate.
