1. Draw a sketch of the human body. Below the sketch, list 5
areas of the body in which you think cell division is most
rapid. Why do you think cells in these areas divide most
rapidly? [Eventually check you answer against research to
verify your answer] [5]
2. What is meant by the term Cell Specialization? [1]
3. Why is cell division important? [3]
4. Why is the division of the nuclear material necessary during
cell division? [1]
5. How do the new cells formed during cell division compare
with the initial cell? [1]
6. A human cell has 46 chromosomes. After the cell has
undergone mitosis, how many chromosomes would you expect
in each cell? [1]
7. Following Telophase and Cytokinesis, the single strands of
genetic material duplicate. Why is the duplication of the
genetic material important to the cell? [1]
8. What is the longest stage of the cell cycle for the average
cell? [1]
9. Explain why different kinds of cells in the body might live for
different lengths of time. [1]
10. At which time of year would mitosis in a plant occur most
frequently? Explain why? [1]
11. Some drugs that combat cancer inhibit mitosis. What effect
might this have on healing times? [1]
12. Describe the daughter cells that would be formed if
during mitosis, all of the chromosomes lined up on one side of
the equator instead of along the equator. Do you think
either daughter cell would be viable? Explain your answer.
[2]
13. When you cut the tip of a finger, a scab forms and new
skin appears underneath the scab. If you cut your finger
deeply enough, however, it may take a long time to regain the
feeling at the tip of your finger. Use your understanding of
the cell cycle to explain these observations. [1]
14. How do daughter cells compare genetically to parent cells?
[1]
15. A scientist studying a group of somatic cells notices that
when the cell cycle is complete, half of the daughter cells
have no chromosomes and the other half have 92
chromosomes. In what phase of mitosis did an error most
likely occur. Explain. [1]
16. The image below shows chromosomes in a human cell.
a. What is this representation called? [1]
b. Identify the sex of the individual. [1]
c. Does this individual have the correct number of
chromosomes? [1]
