Mitosis vs. Meiosis
1. Complete the concept map comparing mitosis and meiosis. Use the
following terms, each term can be used one or more times: diploid
cell, one cell division, four haploid cells, parent cell, two cell
divisions, body cell, same, chromosomes, gamete-producing cell,
half, two diploid cells.
2. Define homologous chromosome. __________________________
______________________________________________________
3. Define sister chromatids. _________________________________
______________________________________________________
4. Describe 2 parts of meiosis that are similar to mitosis.
a. ________________________________________________
________________________________________________
b. ________________________________________________
________________________________________________
5. Identify whether each process below occurs during mitosis, meiosis,
or both.
a. Sister chromatids separate __________________________
b. Haploid cells are formed ___________________________
c. Cell division occurs once ___________________________
d. Homologous chromosomes pair _____________________
e. 4 haploid cells are the final result ____________________
f.
Crossing over occurs ______________________________
Parent Cell
g. Cell division occurs twice __________________________
h. Replicated chromosomes line up in the middle of the cell __________________________
i.
2 diploid cells are the final result _____________________________________________
6. Define crossing over. ____________________________________________________________________________
______________________________________________________________________________________________
What phase does it occur? ________________________________________________________________________
7. Does the parent cell in Mitosis start off as diploid or haploid? ______________________ Are the resulting cells at
the end of Mitosis diploid or haploid? ___________________________
8. Does the parent cell in Meiosis start off as diploid or haploid? _____________________ Are the resulting cells at
the end of Meiosis diploid or haploid? ____________________________
9. How does the number of chromosomes in a sex cell compare with the number of chromosomes in the parent cell?
______________________________________________________________________________________________
A
10. Identify the phase in the cell to the left. _____________________________
11. What is the name of process A that ensures genetic variation?
___________________________________
12. Identify the phase in the cells to the left. _______________________
13. What is happening to the nuclear envelope? ______________________________
14. Identify the phase in the cell to the left. _________________________ What is being
separated? ___________________________________________________
This diagram is a general
overview of what occurs
during Mitosis and
Meiosis, but the specific
phases have not be
labeled for you!!!
