Portage Microbiology BIOD171 FINAL EXAM
1. Nucleus: contains genomic content in eukaryotic cells
2. Endoplasmic reticulum: series of membrane enclosed sacs and interconnected tubes
3. Lysosomes: contain hydrolytic enzymes for digestion
4. Chloroplast: Site of photosynthesis
5. Briefly explain how a Scanning Electron Microscope (SEM) forms an image of a
microscopic specimen.: Answer: An image is formed from the interactions of electrons as they reflect ott (not
through) the surface of the specimen. Samples are coated in either gold or palladium to enhance electron reflections. The
reflection is seen in 3-D rendering.
6. Legionnaires: legionella
7. Wound botulism: Clostridium botulinum
8. Impetigo: staph auerus
9. Septicemic plague: yersina pestis
10. Yeast: Eukaryote
11. Mycobacterium: Prokaryote
12. Algae: Eukaryote
13. flu virus: neither eukaryote or prokaryote
14. Phototroph: utilize photons to generate ATP from ADP
1/9
, 15. lithotroph: remove electrons from inorganic molecules
16. autotroph: obtain their source of carbon from inorganic molecules
17. chemotroph: acquire energy from preformed chemicals in the environment
18. A researcher is looking to solidify an agent for growth media. What polysac-
charide substance would he or she use?: agar
19. Place the following viral life cycle steps in order beginning with viral attach-
ment (3points) and provide a description of "UNCOATING" (1 point).: 1-Attach- ment:
2- Entry:
3- Uncoating: the viral capsid disassembles 4-
Replication:
5- Release:
6- New infection:
20. The action of alcohol during Gram staining is .: Decolorizes the cell
2/9
