  2. Plant cells deposit vesicles containing cell wall building blocks on the metaphase plate; animal cells form a cleavage furrow.

  3. The structural proteins of plant cells separate the two cells; in animal cells, a cell membrane separates the two daughter cells.

  4. Plant cells divide after metaphase but before anaphase; animal cells divide after anaphase.
