  3. Prophase • The nucleoli disappears and changes occur in both the nucleus and the cytoplasm. • Chromatin fibers become more coiled and fold into chromosomes. • Chromosomes become chromatid joined at a centromere. • In the cytoplasm mitotic spindles form made of microtubules and proteins arranged between two centrosomes.

  4. Animal Plant

  5. Metaphase • The centrosomes are now at opposite ends of the cell. • The chromosomes convene on the metaphase plate- the plane between the two poles; middle area • The centromers of all the chromosomes are lined with one another and the sister chromatids straddle the metaphase plate. • The entire apparatus of microtubules is called the spindle because of its shape.

  7. Anaphase • In this phase the sister chromatids are separated. • Each chromatid is now considered a full fledged chromosome. • The once joined sisters begin to move to opposite poles of the cell. • At the same time the poles of the cell move farther apart andeach have equal number of chromosomes.

  9. Telophase • The nonkinetochore microtubules elongate cell more. • The daughter nuclei form at two poles of the cell. • Nuclear envelopes arise from the fragments of the parent cells. • Further reversal of prophase and prometaphase events the chromatid fibers of each chromosomes becomes less tightly coiled. • Mitosis is complete because of the splitting of two nucleolus creating identical nuclei. • Cytokinesis- the diffusion of cytoplasm is well on the way by this time.
