Animal Cellat Interphase

Plant Cellat Interphase

Early ProphaseCentrosomes have duplicated.Chromatin is condensing into chromosomes, and the nuclear

envelope is fragmenting.

ProphaseNucleolus has disappeared, and

duplicated chromosomes are visible. Centrosomes begin moving apart,

and spindle is in process of forming.

PrometaphaseThe kinetochore of each chromatid is

attached to a kinetochore spindle fiber.Polar spindle fibers stretch from each

spindle pole and overlap.

MetaphaseCentromeres of duplicated chromosomesare aligned at the metaphase plate (centerof fully formed spindle). Kinetochore spindle

fibers attached to the sister chromatidscome from opposite spindle poles.

AnaphaseSister chromatids part and become daughterchromosomes that move toward the spindle

poles. In this way, each pole receives the samenumber and kinds of chromosomes as the parent cell.

Telophase Daughter cells are forming as nuclear envelopes and

nucleoli reappear. Chromosomes will become indistinct chromatin.
