Chapter 12 & 13 (Cell Division) Review

1. Draw and label a chromosome.

2. Draw and label the Cell Cycle. What happens in each phase?

3. If there are 24 chromosomes in a plant cell in G₁, what is the diploid number? How many chromatids? What is the haploid number? What is the number of centromeres?

4. What are the stages of mitosis? What occurs at each stage?

5. Compare a cell plate to a cleavage furrow. What is the difference? What would be the advantage of each?

6. What are checkpoints? Where are the checkpoints in the cell cycle? Which checkpoint is the most important one?

7. Define cyclins, cyclin-dependent kinases (Cdk) and MPF. How do they regulate the cell cycle?

8. What happens when a cell enters G₀? What is the purpose? List some examples of cells that are usually found in G₀.

9. Compare and contrast sexual reproduction to asexual reproduction.

10. How does sexual reproduction increase variation?

11. What phases of meiosis increase variation? How?

12. Compare and contrast mitosis to meiosis.
