SCCS AP Biology Chapter 9 Study Guide
Name:
1. Know the sequence of stages in the cell cycle. Know the substages of interphase and the M Phase.
2. Which stages of the cell cycle have critical checkpoints that control the cell cycle? Know the
mechanism of each checkpoint.
3. In which stage does the cell grow and replicate organelles?
4. Can cells in the G0 stage reproduce? Give an example of such cells.
5. What is apoptosis?
6. What is the longest phase of the cell cycle?
7. Some body cells never divide after they are created. What stage of the cell cycle do these cells
attain?
8. If a cell went through mitosis but not cytokinesis, how would it appear? How about a cell that
went through cytokinesis but not mitosis?
9. What protein prevents skin cells with damaged DNA from developing into skin cancer?
10. What is the difference between a haploid and diploid cell?
11. What is a chromosome? Know its function and its composition.
12. If organism A has more chromosomes than organism B, does this mean organism A has more
genetic information than organism B?
13. How does the genetic information of eukaryotes differ from that of prokaryotes?
14. How many chromosomes does a human somatic cell have? How many chromosomes does a
human gamete cell have?
15. What event signals the start of anaphase?
16. Describe what happens during metaphase.
17. How does cytokinesis differ between plant cells and animal cells?
18. What is the function of mitosis? What is the product of mitosis?
19. If chromosomes are mutated, what cell organelle is abnormal?
20. How does angiogenesis relate to cancerous cells? How does metastasis relate to cancerous cells?
21. How does a proto-oncogene differ from an oncogene?
22. What is a nucleoid?
23. Why don’t bacteria have to go through mitosis in order to reproduce?
24. In what stages of the cell cycle are chromosomes visible?
25. How are centromere, kinetochore, chromatids, and chromosome related?
26. How are spindle fibers related to chromosomes?
FRQ’s:
In Class:
In order for organisms to grow they must produce new cells and each cell must maintain the same genetic
identity as the original cell. This will ensure the new cells will function properly and survive.
A) Starting with interphase, explain how the events of the cell cycle ensure that each new cell will be
genetically identical to the original.
B) What features of the prokaryotic genetic material eliminates the need for mitosis to ensure identical
daughter cells?
Take-Home: The cell cycle is a heavily regulated process. Many different diseases can result from the abnormal
regulation. Explain how the cell cycle is impacted and how our understanding of the regulation process is
allowing medical scientists to develop cures in the areas listed below.
A) Spinal cord injuries
B) Breast cancer
C) Progeria
