Essential Biology 02.5: Cell Division (Mitosis)
1. Distinguish between cell division and mitosis.
2. Explain why prokaryotes do not need to use mitosis in their division.
3. What is the outcome of one cycle of cell division by mitosis?
a.
b.
c.
d.
Two haploid daughter cells
Two diploid daughter cells
One diploid daughter cell
Four haploid daughter cells
4. List four processes that involve mitosis.
5.
On the pie chart below, mark the approximate relative amount of time spent in each of the
stages of the cell cycle. Include interphase, prophase, metaphase, anaphase, telophase and
cytokinesis.
6.
What are the three stages of interphase and what happens during each one?

9. Explain how mitosis produces two genetically identical nuclei, referring to:
S-phase:
Chromosome number:
Metaphase:
Anaphase:

Distinguish between mitosis and cytokinesis.
11. Cancer is an increasing global health concern, related to problems with cell division.
a. What is a tumour?
b. Where can tumours occur? Where are they most likely to occur?

12. The following data are taken from a CA – a journal for cancer clinicians, 2009. The graph below
compares the incidence and mortality for the 15 most common cancers in males, in the
developing and developed worlds.
Source: http://caonline.amcancersoc.org/cgi/reprint/49/1/33.pdf
a. Distinguish between incidence and mortality.
b. Use the graph to estimate these total global statistics:
Type of cancer
Incidence (thousands)
Mortality
Lung
Prostate
c. Using the data from c., calculate and compare the survival rates for lung and prostate cancer.
d. List three cancers which have higher prevalence rates in developed countries than in
developing. Can you suggest reasons for this?
