Question

When plant cells undergo cytokinesis, they use ____ because their cell wall keeps them from pinching.

A) Cleavage furrow
B) Cell plate
C) Spindle fibers
D) Centromeres

Answer 1

When plant cells undergo cytokinesis, they use a cell plate because their cell wall prevents them from forming a cleavage furrow. Instead of a cleavage furrow, a cell plate forms between the daughter cells, which eventually merges with the cell wall at the periphery of the cell.

Step-by-step explanation:

When plant cells undergo cytokinesis, they use cell plate because their cell wall keeps them from pinching. In plant cells, a cleavage furrow is not possible due to the rigid cell walls surrounding the plasma membrane. Instead, a cell plate forms between the daughter cells, which eventually merges with the cell wall at the periphery of the cell. Enzymes use the accumulated glucose to build a new cell wall of cellulose and the Golgi membranes become the plasma membrane on either side of the new cell wall.
