Cell appears to be resting. Prophase Chromosomes become visible. Centrioles and spindle fibers appear Metaphase Chromosomes line up in the middle. Spindle fibers attach to the centromere of the chromosomes Anaphase Duplicated chromosomes separate. Cytoplasm division begins Telophase Nuclear membrane reform. Cytoplasm division occurs. Division of cytoplasm. Different between animal and plant cells.
