  3. Differentiate between the following: centromere, centrioles, centrosomes; chromatin and chromosomes; sister chromatids and daughter chromosomes; interphase, mitosis, cytokinesis.
  4. Differentiate mitosis in a plant cell from mitosis in an animal cell.
  5. Describe the G1, G2, and Spindle assembly checkpoints.
  6. Describe five factors that control the cell cycle.
  7. Describe the behavior of cancer cells.
  8. Enumerate the causes of, and therapies for cancer.
  9. Justify the need for meiosis.
  10. Flowchart the events in the different stages of meiosis.
  11. Enumerate 5 differences between mitosis and meiosis.
  12. Explain how meiosis contributes to variation among individuals.
  13. Represent the similarities and differences between spermatogenesis and oogenesis in a Venn diagram.
  14. Explain how errors in cell division may result in aneuploidy or polyploidy.
