Plant cell cytokinesis differs from animal cytokinesis because plant cells
Ause a contractile ring to pinch the membrane
Bskip cytokinesis entirely
Cbuild a cell plate that grows outward into a new wall
Dsplit via random fission, like bacteria
Answer & Solution
Correct answer: C. build a cell plate that grows outward into a new wall
Plant cells have a rigid cell wall, so a pinching furrow is mechanically impossible. They build a new wall from the centre out: vesicles fuse to form the cell plate, which extends until it fuses with the existing walls. Contractile rings are the animal-cell mechanism.
