1) Cytokinesis begins in

A) Prophase

B) Metaphase

C) Anaphase

D) Telophase

 

I think it's late anaphase not sure though

 

2) Which phase of mitosis is the longest?

 

Well, I remember my teacher saying it was metaphase, but textbook and other people on yahoo answers say its prophase, so i just didn't know who to go with?

What does cytokinesis mean? What happens during cytokinesis?

The first phase of mitosis is the prophase.

Metaphase is the longest phase in mitosis.

 

During cytokinesis the cytoplasm is divided by the construction of a contractile ring around the middle of the cell. This ring narrows and a cleavage furrow appears and grows inward. When it completes and there also are septin filaments beneath the cleavage furrow the cell does the actual division. After that the microtubules used in the mitosis process are reorganized back into the cytoskeleto and the cell is back in the normal interphase.

 

Plant cells do not use a contractile ring or a cleavage furrow during cytokinesis.

Plant cells instead create a cell plate.

Really should've added "questions for you to think about" to my earlier post. :/
