|! |! |! |! |! |! |! |! |! |! |!
epithet names. - Correct answer ✔Designed by Carolus Linnaeus each living
|! |! |! |! |! |! |! |! |! |! |!
organism is assigned two names. The genus is the first name and is always
|! |! |! |! |! |! |! |! |! |! |! |! |! |!
capitalized. The species name follows and is not capitalized.
|! |! |! |! |! |! |! |!
Differentiate among the major characteristics of each group of
|! |! |! |! |! |! |! |! |!
microorganisms. - Correct answer ✔Most common shapes of bacteria: |! |! |! |! |! |! |! |! |!
Bacillius (rodlike); Coccus (spherical or ovoid); spiral (corkscrew or curved).
|! |! |! |! |! |! |! |! |!
Archaea: - Correct answer ✔consist of prokaryotic cells and don't have cell
|! |! |! |! |! |! |! |! |! |! |! |!
walls. They live in extreme environments
|! |! |! |! |!
Fungi: - Correct answer ✔eukaryotic organisms have distinct nucleus. Can be
|! |! |! |! |! |! |! |! |! |!
uni/multicellular
|!
,Protozoa: - Correct answer ✔eukaryotic; unicellular. Most are parasites,
|! |! |! |! |! |! |! |! |!
names means "first animals"
|! |! |!
Algae: - Correct answer ✔uni/multicellular that obtain nourishment through
|! |! |! |! |! |! |! |! |!
photosynthesis.
Viruses: - Correct answer ✔non cellular that are parasites of cells.
|! |! |! |! |! |! |! |! |! |! |!
Structurally simple, difficult to kill. Smaller than bacteria.
|! |! |! |! |! |! |!
All organisms are classified into three basic domains. What are the domains?
|! |! |! |! |! |! |! |! |! |! |! |!
- Correct answer ✔Bacteria, Archaea, and Eukarya.
|! |! |! |! |! |!
Explain the importance of observations made by Hooke and van
|! |! |! |! |! |! |! |! |! |!
Leeuwenhoek. - Correct answer ✔Hooke discovery marked that beginning of |! |! |! |! |! |! |! |! |! |!
cell theory - that all living things are composed of cells
|! |! |! |! |! |! |! |! |! |!
VAm Leeu - observation of live microorganisms using his simple microscope
|! |! |! |! |! |! |! |! |! |!
Compare the theories of spontaneous generation and biogenesis. - Correct
|! |! |! |! |! |! |! |! |! |!
answer ✔Spontaneous generation is that life could spontaneously generate
|! |! |! |! |! |! |! |!
Biogenesis- the theory that living cells can arise only from preexisting living
|! |! |! |! |! |! |! |! |! |! |! |!
cells.
Identify the contributions to microbiology made by Needham, Spallanzani,
|! |! |! |! |! |! |! |! |!
Virchow, and Pasteur. - Correct answer ✔Needham claimed that
|! |! |! |! |! |! |! |! |!
microorganisms could arise spontaneously from heated nutrient broth |! |! |! |! |! |! |!
, Spallanzani suggested needham results were due to microorganisms in the air
|! |! |! |! |! |! |! |! |! |!
that were entering his broth.
|! |! |! |! |!
Virchow biogenesis |!
Pateur experiments that formed the basis for aseptic technique.
|! |! |! |! |! |! |! |!
Identify the importance of Koch's postulates. - Correct answer ✔Proved that
|! |! |! |! |! |! |! |! |! |! |!
microorganisms caused disease |! |!
Explain how Pasteur's work influenced Lister and Koch. - Correct answer
|! |! |! |! |! |! |! |! |! |! |!
✔Because he participated in the development of germ theory (idea that
|! |! |! |! |! |! |! |! |! |! |!
microorganisms might cause disease)Coined the term vaccine and that the |! |! |! |! |! |! |! |! |! |!
protection from disease or recovery is called immunity, and discovered that
|! |! |! |! |! |! |! |! |! |! |!
avirulent bacteria can be used to cure fowl cholera
|! |! |! |! |! |! |! |!
Identify the importance of Jenner's work. - Correct answer ✔He
|! |! |! |! |! |! |! |! |! |!
demonstrated that inoculation with cowpox material provided humans with
|! |! |! |! |! |! |! |! |!
immunity from small pox |! |! |!
Identify the contributions to microbiology made by Ehrlich and Fleming. -
|! |! |! |! |! |! |! |! |! |! |!
Correct answer ✔Ehrlich introduced an arsenic containing chemical called
|! |! |! |! |! |! |! |! |!
salvarsan to tx syphilis |! |! |!
Flemming observed that mold (penicillium) inhibited the growth of a
|! |! |! |! |! |! |! |! |! |!
bacterial culture. |!
