Select all that apply. A) The cell plate expands along the plane of division, and when the plate fuses with the plasma membrane, the cytoplasm is partitioned into two new cells. B) After telophase, the contractile ring constricts the plasma membrane and forms a cleavage furrow. C) The contractile ring reaches its smallest diameter, and the spindle microtubules are cut as vesicles form the new membranes that separate the two new cells.
