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. __________________________

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 ______________________________
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? ____________________________
