Metaphase: This is the second stage of cell division. Spindle fibers attach to the chromosomes in order to separate them.

Anaphase: This is the third stage. The chromosomes are pulled away from each other towards opposite sides of the cell

Telophase: This is the last stage of cell division. The chromosomes have reached the opposite sides of the cell and now the nuclear envelope is reforming around the now separated chromosomes and two separate cells are formed.
