Name three reasons why cells reproduce. 1.5 pts
Draw a picture of a prokaryotic chromosome. Which organisms have this type of chromosome?
1.5 pts
Draw and label a picture of how eukaryotic DNA is packaged into chromosomes. In your drawing
include DNA, histone proteins, nucleosome, 30 nm fiber, looped domain, condensed chromosome,
sister chromatids, and centromere. Name two organisms that have eukaryotic chromosomes. 5
pts
Draw a picture of cell division in bacteria. 2 pts
The eukaryotic cell cycle is a repeating sequence of growth and division. It contains G1, S, G2,
mitosis and cytokinesis. Describe what happens in each of these stages. 2.5 pts
Draw a picture of cell division (mitosis) in eukaryotic cells. Include and label all four stages in
correct order. Your cell should have three chromosomes in prophase. 4 pts
Differentiate between cytokinesis in plant and animal cells. 1 pt
Your textbook describes three checkpoints in the cell cycle that ensure that the cell is ready to go
to the next stage. List these three checkpoints and for each checkpoint identify a cause that would
result in a delay of the next phase of the cell cycle. 3 pts
How does cancer relate to the cell cycle? 1 pt
Name one advantage and one disadvantage of asexual reproduction. 1 pt
Name one advantage and one disadvantage of sexual reproduction. 1pt
Choose one type of asexual reproduction and explain how it occurs. 1 pt
Compare the number of sets of chromosomes between a haploid cell and a diploid cell. In animals,
which cells are haploid? Which are diploid? 2 pts
What is the role of meiosis in sexually reproducing organisms? 1 pt
Explain how the chromosome number is reduced from diploid to haploid through the stages of
meiosis. 2 pts
Name three differences between mitosis and meiosis. 1.5 pt
What are three mechanisms of genetic variation? 1.5 pt
What is a diploid life cycle? Give an example of organism that has this type of life cycle. 1 pt
What is a haploid life cycle? Give an example of organism that has this type of life cycle. 1 pt
What is alternation of generations? Which organisms have it? 1pt
Where are male gametes (sperm cells) produced? What path do they take to exit the body? Be
specific. 2 pts
List the components of semen. 1.5 pts
What are the functions of ovaries? 1 pt
Summarize the path of an egg through the female reproductive system. 2 pts
Explain how the ovarian cycle is related to the menstrual cycle. 2 pts
List the three stages of the ovarian cycle and explain what happens in each stage. 3 pts
Differentiate between the terms fertilization and implantation. 1 pt
Define the following terms: embryo, amnion, chorion, umbilical cord, placenta, and fetus. 3 pts
Choose four common STDs in the US and briefly describe each. 4 pts
How can you avoid being infected by an STD? 1 pt
