Mitosis
Prophase: The two round objects above the nucleus are the centrosomes. The chromatin is condensing into chromosomes.
Prometaphase: The nuclear membrane disintegrates, and microtubules have invaded the nuclear space. These microtubules can attach to kinetochores or they can interact with opposing microtubules.
Metaphase: The chromosomes align at the metaphase plate.
Anaphase: The chromosomes split and the kinetochore microtubules shorten.
Telophase: The decondensing chromosomes are surrounded by nuclear membranes. Cytokinesis has already begun; the pinched area is known as the cleavage furrow.
