Bacteria/Virus review
1. What are the lytic and lysogenic cycles and explain the difference between them.
They are reproduction cycles of bacteria. Lytic- Virulent, Lysogenic Cycles-nonvirulent (also becomes part of the host cells DNA)
2. Identify the steps of the lytic cycle. See PPT
3. Explain the steps of the lytic cycle. See PPT
4. How are viruses spread in humans (list several ways)? Air, body fluids
5. Are viruses living or nonliving? Support your answer. NON- does not maintain
homeostasis, grow and develop, or metabolize
6. Are bacteria living or nonliving? Support you answer. Living – all characteristics
7. What are the basic shapes of viruses? Give examples for each. Helical,
icosahedral
8. What basic structures do all viruses have (should be 2 structures)? Genetic
material and capsid
9. Explain RNA, DNA, prions, viroids, and retroviruses and give examples of each.
(see notes)
10. What are the 3 basic shapes of bacteria? Round, rod, spiral
11. What are the 4 groups of bacteria? Diplo, strepto, staphylo, tetra
12. Explain Gram-positive and Gram-negative. Be sure to give the color it turns and
its significance. Postitive- turns purple- treatable, negative-turns pink-not treatable
13. What enables bacteria to be gram-negative? Extra layer of fat
14. Explain sexual and asexual reproduction in bacteria: Be sure to tell me what the
process is called and what happens. Binary Fission: Asexual, Conjugation: Sexual
15. List the different phylums of bacteria and give an example of each.
16. What are the 2 kingdoms in bacteria? Archeabacteria, Eubacteria
17. Why did they split Monera into 2 kingdoms? Different characteristics: missing
protein called peptidoglycan.
18. Explain and Give examples of the 3 types of Archeabacteria. Methanogens,
Thermoacidophilles, Halophilles (see notes for examples)
19. Who was the first person to see bacteria under a microscope? Leeuwenhoek
20. Are bacteria prokaryotic or eukaryotic? Support your answer. Prokaryotic: no
nucleus
21. What are chemoautotophs and nitrogen-fixing bacteria? Give examples
22. Give the function of the following structures of a bacterium: DNA (nucleoid),
cytoplasm, cytoplasmic (cell) membrane, pili, flagella, capsule, cell wall,
ribosomes. (see notes)
23. Define anaerobic, aerobic, facultative anaerobic, saprophyte, conjugation, binary
fission. (See notes)
24. Draw the following: Diplococcus,
Streptobacillus,
25. Staphylobacillus,
Tetraspirillus,
Diplospirillus,
Streptococcus
26. Name each of the following bacteria.
1. Diplobacillus 2. Streptococcus
5.Tetrabacillus
6. Diplococcus
3. Streptobacillus
7. Diplospirillus
4. Staphylococcus
8. Staphylospirillus
25. Label the following pictures/Diagrams.
*** be able to label the diagram of the lytic cycle and discuss differences between both
the lytic and lysogenic cycles.
