Cell Reproduction
Name:________________________
Part I. Meiosis vs. Mitosis. For each statement below, identify whether it refers to mitosis or
meiosis. Write “MI” for mitosis and “ME” for Meiosis
1. Occurs in body cells, such as skin or bones. ______
2. Occurs in sex cells. _____
3. Makes eggs or sperm. ______
4. Makes haploid cells. ______
5. Makes diploid cells. ______
6. Produces cells that are genetically identical to the parent. ______
7. Produces cells that are genetically different from the parent. ______
8. Produces 2 cells. _______
9. Produces up to 4 cells. _______
Part II. Asexual vs. Sexual reproduction. Identify whether each statement below refers to sexual
or asexual reproduction. Write an “A” for asexual or an “S” for sexual
10. Involves 2 parents. _______
11. Produces offspring that are identical to the parent. ______
12. Produces offspring that are different from the parent. ______
13. Examples include processes such as binary fission (dividing) in bacteria, or budding in yeast
or hydra. _______
14. Involves the union of sex cells – eggs and sperm. _______
15. Involves only 1 parent. _______
16. Identify the phases of mitosis:
A. _____________
B. _____________
C. _______________ D. _______________

Part III. Meiosis questions.
18. What type of chromosomes are lined up in the middle of the cell during metaphase of meiosis
I (hint: remember they are in pairs)?
19. What is the total number of chromosomes in each of two resulting cells from Meiosis I if the
parent cell has a diploid number of 12 to start?
20. Explain what it means when chromosomes cross over. Remember the crossing over occurs
during prophase I of Meiosis?
21. How does crossing over contribute to genetic variability?
22. What is being pulled apart in anaphase of meiosis II (hint: it’s not the homologous pairs, but
something else just like what gets separated in mitosis)?
23. How many cells result from meiosis compared to mitosis?
Meiosis questions continued
Use this diagram to answer Questions 22–24.
24. What does the diagram show?
25. During what phase of meiosis does this process occur?
26. What is the result of this process?
Comparing Meiosis and Mitosis
27. Complete the table to compare meiosis and mitosis.
Mitosis
Meiosis
Form of reproduction (choose
from sexual or asexual)
Number of daughter cells
(choose from 2 or 4)
Change in chromosome number
(choose from cuts in half or
stays the same)
Number of cell divisions (choose
from 1 or 2)
Difference in alleles between
parent cell and daughter cells
(choose from genetically
identical to genetically different)
28. Examine the mitosis and meiosis diagrams shown below.
Identify at least three differences between mitosis and meiosis:
a. ____________________
b. ___________________
c. ___________________
For Questions 29–34, complete each statement by writing the correct word or words. Use the
word bank below:
Remember mitosis does not change the chromosome number, and meiosis cuts the
chromosome number in half.
Two (used twice)
Sixteen (used twice)
Haploid
Even
Four
Eight
Ten
29. A diploid cell that enters mitosis with 16 chromosomes will divide to produce
daughter cells. Each of these daughter cells will have
chromosomes.
30. If the diploid number of chromosomes for an organism is 16, each daughter cell after mitosis will
contain
chromosomes.
31. A diploid cell that enters meiosis with 16 chromosomes will pass through
divisions, producing
daughter cells, each with
chromosomes.
32. Gametes have a
cell
number of chromosomes.
33. If an organism’s haploid number is 5, its diploid number is
.
34. While a haploid number of chromosomes may be even or odd, a diploid number is always
.
