Review Questions
1.
What are functions of the cytoskeleton?
2. How do the cytoskeleton and the cytoplasm contribute to a cell’s shape?
3. What characteristics do chloroplasts and mitochondria share?
4. What structure do you find in plant cells that you do not find in animal cells?
5. In a cell, what is the purpose of the nucleus?
6. If you were looking through a microscope at an unknown cell, how might you determine whether it
was a plant cell or an animal cell?
7. What function does the cell wall perform in a plant?
8. What are the organelles that are involved in protein production? Briefly explain where proteins are
made, modified, and packaged within the cell.
9. Explain how the endoplasmic reticulum, mitochondrion, and Golgi apparatus are structurally
similar?
10. Explain what mitochondria do and why evidence suggests that they might have descended from
free-living prokaryotes in the evolutionary past.
11. Medicine, alcohol, and many drugs are detoxified in liver cells. Why do you think the liver cells of
