Mitosis – Nuclear Division

Cytokinesis – Cytoplasm Division

Some initial vocabularyChromatin vs. ChromosomeChromosome – replicated vs. unreplicatedChromatid (sister) – [Why is it important that sister chromatids are identical?]

CentromereCentriole (Centrosome)

Cytokinesis

Cytokinesis takes place as telophase is ending.

Cytokinesis is the division of the cytoplasm. It occurs after the division of the nucleus.

Mitosis vs. Cytokinesis

MITOSIS

Division of the nucleus

Results in an identical product.

(Mitosis produces clones.)

CYTOKINESISDivision of the cytoplasm.

Results in a similar product.

The Difference Between Plant and Animal Cell Division

ANIMAL CELL

Cytoplasmic constriction

Uses centrioles

PLANT CELL

Formation of a cell plate

(no constriction)

No centrioles
