Principles of Biology : Quiz
11 Study Guide
We will take Quiz 10 on Wednesday, November 5. I
recommend that you answer these questions yourself or with classmates.
This not a graded assignment, nothing is to be turned in. These
questions are just to help you prepare for this quiz.
Reading: You should read Chapter 10, Section 10.7 (page 197) and all
of Chapter 11. This quiz will cover the basics of meiosis and a
comparison with mitosis.
There are flashcards and animations on the Aris site you should study.

Questions to consider:
Cell Cycle and the Control of the Cell Cycle
1) What is meant by the term "cell cycle?"
2) What are the basic stages of the cell cycle?
3) What are the major three checkpoints of the cell cycle?
4) What do all cancers have in common?
5) What is the p53 gene? What role does the p53 protein play in the
cell cycle?
6) What happens if a cell has a mutated p53 gene?
7) p53 is considered a "tumor-suppressor gene." Explain.
Sexual Life Cycles - You should know the life cylce of each of the
following:
- Ulva (handed out in class, see link on calendar)
- Moss (handed out in class, see link calendar)
- Animals (Figure 11.2.b. and figure 11.3)
- Plants (Figure 11.2.c)
You should be able to identify the haploid phase, the diploid phase,
the process of mitosis and the process of meiosis. You should be able
to apply the following terms: gamete, egg (ovum), sperm, zygote,
blastula, gametophyte, sporophyte, fertilization, meiosis, mitosis,
haploid cells (including spores) ... as appropriate.
Cell Division - Meiosis
8) What type of cell is theoretically capable of undergoing meiosis?
9) What type of cells actually do under go meiosis?
10) What is the typical result of meiosis?
11) What is meant by the terms haploid, diploid, and polyploid?
12) What are the stages of Meiosis I? Describe them.
13) What are the stages of Meiosis II? Describe them.
14) What is "crossing over?" Where does it occur? When does it occur?
15) What is the effect of crossing over? That is, what does it matter?
16) Explain "The Alternation of Generations" as a generalized pattern
which is found in all sexually reproducing species.
17) Describe and explain the major differences between mitosis and
meiosis.
