Prokaryotic Cell Review Questions
SPO VIRTUAL CLASSROOMS

3. What type of cells have peptidoglycan as part of the cell wall? What is the function of peptidoglycan?
4. What is the primary difference between Gram negative and Gram positive bacteria and why is it important?
5. Create a labeled drawing or diagram of a Gram+ cell wall and a Gram- cell wall.
These are review questions are designed to help students better understand the history of microbiology. They are based on materials that can be found on the Prokaryotic Cell Structure & Function Lecture Main Page.

11. Explain passive and active transport of molecules across the plasma membrane.
12. Describe an example of diffusion down a concentration gradient.
13. What would happen to a blood cell if placed in water (a hypotonic environment)? Why would the same thing not happen to a bacterial or a plant cell?
14. Describe factors that may prevent a molecule from moving across a cell membrane?
15. Describe the two types of bacterial glycocalyces that we discussed in class. How do they differ?
16. Why are there more types of cell arrangement for cocci than for bacillus-shaped bacteria?
17. Distinguish between pili, fimbriae, flagella, axial filaments. Give an example of a type of bacteria associated with each type of bacterial cell extension.
6. List all of the species of bacteria that we have studied so far and indicate which are G+ and which are G-.
7. What is the vegetative state of a bacterium and how does it differ from an endospore?
8. Use the list of bacteria that you created for review question #6, and indicate which of these bacteria are able to produce endospores.
9. Are the bacteria that can create endospores all G+, all G-, or are there both G+ and G- endospore producers?
10. Draw and label 5 different bacterial shapes and 5 different bacterial arrangements.
