He's right. The only difference is during telophase instead of the cell membrane pinching off (cytokinesis) like it does in animal cells, a cell wall begins to form between the two daughter cells. T

Plant cells have no centrioles (animal cells have centrioles), so plants have no migration of centrioles to opposite poles. Scientists are still debating the relationship between centrioles and the spindle, but plant cells DO have a spindle, so they may be using another mechanism to produce it.

Plant cells do cytokinesis differently, but cytokinesis is not technically a part of actual mitosis. Plant cells form a cell plate across the equator of the soon-to-be-divided cells. The new plasma membranes and cell walls form next to the cell plate. Animal cells just pinch in near the middle, forming a cleavage furrow. The cells continue to pinch in until they pinch completely into two cells. Think of it almost like putting a belt around the cell and pulling it more and more tightly.

I don't know.
The biggest difference would be during the actual cell division -- the cell well has to weaken at the point of division, and new cell wall has to form between the new daughter cells.
I hope someone gives you a better answer.
