1. List 5 basic groups of microbes - ✔✔1) Bacteria
2) Fungi (Molds)
3) Viruses
4) Protozoa
5) Algae (will not be studies in Jeffery's
... [Show More] class)
2. What is a multicellular organisms composed of eukaryotic cells, with the cells are organized into tissues and have cell walls. This organism obtains nutrients by photosynthesis and absorption. - ✔✔Plantae Kingdom
3. What is a multicellular organisms composed of eukaryotic cells. The cells are organized into tissues and lack cell walls. They do not carry out photosynthesis and obtain nutrients primarily by ingestion. - ✔✔Animalia Kingdom
4. Simple, predominately unicellular eukaryotic organisms. Examples includes slime molds, euglenoids, algae, and protozoans - ✔✔Protista Kingdom
5. A gram stain of discharge from an abcess shows cocci in irregular, grape-like clusters. What is the most likely genus of this bacterium? - ✔✔Staphylococcus:An arrangement of cocci in irregular, often grape-like clusters is called a staphylococcus arrangement. The genus Staphylococcus is named after this arrangement.
6. State the diameter of an average-sized coccus-shaped bacterium. - ✔✔Staphylococcus:0.5-1.0 micrometer
7. What is the study of Microbiology? - ✔✔The study of microscopic organisms. Organisms that need to be seen under a microscope.
8. Name three characteristics of microorganisms. - ✔✔1) Very small cells (measured in micrometer 10 to the -6 or nanometer 10 to the -9)
2) Most are unicellular (single cells)
3) Very simple cell structure (not complex)
9. What are the three places in the human body where there should be NO bacteria? (and if there is bacteria in any of these places we have a problem!) - ✔✔1) The Brain and Spinal cord
2) Heart and blood vessels
3) Kidneys
10. What are the five general Kingdoms? - ✔✔1) Animal Kingdom
2) Plant Kingdom
3) Monera Kingdom (includes the bacteria)
4) Fungi Kingdom (Yests and Molds)
5)Protista Kingdom
11. What are the three Kingdoms that we will use in Microbiology? - ✔✔1. Monera Kingdom (includes the bacteria)
2. Fungi Kingdom (Yests and Molds)
3. Protista Kingdom
12. What are the measurement in meters that are used in Microbiology? - ✔✔centi c 0.01
milli m 0.001
micro μ 0.000,001
nano n 0.000,000,001
13. Define Peptidoglycan. - ✔✔A protein sugar complex that is in the cell wall of most bacteria.
14. What are the three forms that a spiral microbe can come in? - ✔✔Vibrio (U shaped)
Spirillum (thick like a sausage)
Spirochete (thin like angel hair pasta)
15. What are the shapes that a bacillus can come in? - ✔✔Bacillus (one cigar looking object)
Streptobacillus (several cigars attached to one and other.
Coccobacillus (a smooshed cigar that looks a little bit like an egg).
16. What are the general effects of an endotoxin? - ✔✔1) Stimulates inflammation
2) Inflammation becomes excessive and dangerous to humans.
3) endotoxin causes damage to animal cell membranes causing leakage of cell fluid-causing our cells to die.
17. What is a "Pure Culture" - ✔✔A pure culture is one in which all the organisms are descendants of the same organism.
18. What is "Aseptic Techinque"? [Show Less]
