Which event most accurately describes cytokinesis?
Talja [164]
Cytokinesis is the process wherein actual division of the cell, including the cell membrane and the cytoplasm, from the parent cell to two daughter cells. The correct answer in this question is "the metaphase plate is the beginning area for cytokinesis" as the metaphase plate dictates the midpoint of the cell. A cell with a cell wall (plant cell, for example) cannot perform cytokinesis with a cleavage furrow but with a cell plate. Phragmoplast only develops in plant cells. Lastly, cytokinesis only starts after telophase.
