Biology 1 Cell Cycle (Mitosis & Meiosis) Review 2011
Name:
Period:
1. If the cell grew instead of dividing:
a. the cell’s _DNA_ wouldn’t be able to serve the cells needs anymore
b. also larger cells have a ( greater or lesser) surface area and (greater or lesser)
volume meaning it would be harder to move nutrients and wastes across the
membrane.
2. Why does Mitosis occur (3 reasons)?
 growth and development
 to repair damages cells
 to produce offspring through asexual reproduction
3. What does the cell do before division to ensure that each daughter cell gets one complete set of genetic
information?
________replicates or copies all it’s DNA________________________________
4. Match the following with its definition:
____c__cell division
___f___prokaryotic cell division (Binary
Fission)
___d___eukaryotic cell division (Mitosis)
a. reproduction without the fusion of gametes (don’t need
2 parents)
b. series of events that cells go through as they grow and
divide
c. the process by which a cell divides into 2 new
“daughter cells”
d. includes the two stages: Mitosis and Cytokinesis
__a____asexual reproduction
__h____chromosome
____g__centromere
e. each chromosome consists of two identical
strands; “sister”
f. the simple process of separating the contents of the cell
into two parts used by bacteria.
g. the area where each pair of chromatids is attached
__e____chromatids
___b___cell cycle
h. the very long, tightly coiled continuous piece of DNA
which carries the genetic information from generation to
generation
5. Each chromosome consists of ___2__ “sister” chromatids and is found in the __nucleus__________.
6. Interphase is the period of the cell cycle between cell divisions and consists of __3____ phases.
7. What are the 2 basic stages (parts) of cell division in eukaryotes? ___Mitosis and
Cytokinesis_____________________
8. What order do the phases of Interphase occur? ___________ G1, S, G2______________________
9. What order do the phases of Mitosis occur? ___Prophase, Metaphase, Anaphase, telophase____
10. Draw a chromosome and label the sister chromatids and the centromere.

The diagram represents what? The Cell Cycle
What happens during A? Growth
What happens during B? Synthesis of DNA
What happens during C? Growth, Preparation for Mitosis
A, B, and C together are called ___Interphase__.
What happens during D? Mitosis, the nucleus divides
19. How many chromosomes does a human have? 46
20. If a parent cell has 8 chromosomes before mitosis, how many chromosomes do the daughter cells
have? ____8___
21. Label the following structures and phases of the cell cycle in the picture below: Centrioles
1. Centrioles
2. Chromatin
3. Spindles
4. Interphase/early Prophase
5. Late Prophase
6. Metaphase
7. Anaphase
8. Telophase
9. Cytokinesis
22. With cancer, the cells lose the ability to control __growth_____and begin dividing uncontrollably.
23. The diagram shows two sets of cells: one has cancerous
cells (A) and the other has normal cells (B). Label the
cancerous and normal cells.

Meiosis Review Questions
24. Where in your body (what cells) is the process of Meiosis occurring? _gametes (sex/reproductive
cells)______
25. Match the following:
a. homologous chromosomes exchange portions of their
chromatids
b. reference to a cell that contains only a single set of
chromosomes and a single set of genes; N
c. a mature sexual reproductive cell (sperm or egg) that has
a haploid number that unites with another cell to form a new
organism
d. process where the number of chromosomes per cell is cut
in half through separation of homologous chromosomes in a
diploid cell
e. reference to a cell that contains both sets of homologous
chromosomes; 2N
f. chromosomes that each have a corresponding chromosome
form the opposite-sex parent
g. the cell formed by the union of two gametes
__B___haploid
__F___homologous chromosomes
___D__meiosis
_E___diploid
__C___gamete
__G___zygote
__A___crossing over
26. How many gametes are made during cell division by meiosis? __4 in males, 1 in females________
27. _______MITOSIS_____________ produces 2 genetically identical diploid cells while
___________Meiosis_________ produces 4 genetically different haploid cells.
28. In Mitosis, the new daughter cell is ( different or identical ) to the parent cell.
29. In Meiosis, the new daughter cells are ( different or identical ) from the parent cell.
30. What is being shown in figure 11-1? Describe
the process below: Crossing Over
Figure 11–1
31. Traits can only be inherited from your ( somatic cells or gamete cells ).
32. Prior to cell division, a human skin cell contains 46 chromosomes. Following cell division, each new
daughter skin cell will have ____46_____ chromosomes.
33. If an organisms diploid number is 30, then its haploid number would be __15____.
34. What does a chromosome carry from each generation to the next?
