explaining what is happening in each.

9. What is the chromosome number in the daughter cells produced by mitosis? ________________
10. What will the daughter cells, produced by mitosis, look like?
11. What is asexual reproduction?

13. What is meiosis?
14. What kind of cells are produced by meiosis?
15. Why does meiosis occur?
16. How many phases are involved in meiosis? ________________ .
How many times does the cell divide in meiosis? ___________
17. What is the chromosome number in each cell at the end of meiosis? __________________
18. Complete the following chart for humans undergoing meiosis.
Male
Female
Name of gamete
Where produced in body?
# of gametes produced
from one parent cell
Chromosome # in gamete
19. What is fertilization?
20. What is the chromosome number in a human zygote?
21. What process takes place after fertilization?
22. Complete the following chart to show how mitosis and meiosis compare/contrast.
Mitosis
Meiosis
Function
Location in Body
Number of daughter cells
Change in chromosome number
Number of phases
Number of cell divisions
Difference in DNA between
parent and daughter cells.
23. What biological advantage does sexual reproduction provide over asexual reproduction?
1. Cell division
2. body cells / somatic cells
3. growth and repair
4. PMAT – Prophase, Metaphase, Anaphase, Telophase
5. Prophase – nuclear membrane disappears & spindle fibers form
Metaphase – chromosomes meet in the middle of cell
Anaphase – sister chromatids separate and move to opposite ends of cell
Telophase – two nuclear membranes form around each group of chromosomes, cytokinesis begins
6. Interphase
7. Interphase
8. diploid
9. diploid
10. two
11. identical to the parent
12. no sex cells involved
13. binary fission, budding, vegetative propagation, regeneration, sporulation.
14. binary fission – amoeba; budding – yeast; vegetative propagation – strawberry plants; regeneration – lizard tails;
sporulation – mushrooms
15. cell division in preparation of sexual reproduction
16. gametes / male and female sex cells
17. to maintain the correct chromosome number within a species
18. 8 – Meiosis I and Meiosis II
19. haploid
20. testes
21. four
22. twenty-three (23)
23. ovaries
24. one
25. twenty-three
26. joining of egg and sperm cell
27. forty-six (46)
28. mitosis
