Produce foods and chemical necessary for the survival of humans
Maintain health present on your skin, in your mouth, and in your stomach - CORRECT ANSWER✔✔List
several ways in which microbes affect our lives.
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. - CORRECT ANSWER✔✔
Recognize the system of scientific nomenclature that uses genus and specific epithet names.
Most common shapes of bacteria: Bacillius (rodlike); Coccus (spherical or ovoid); spiral (corkscrew or
curved). - CORRECT ANSWER✔✔Differentiate among the major characteristics of each group of
microorganisms.
consist of prokaryotic cells and don't have cell walls. They live in extreme environments - CORRECT
ANSWER✔✔Archaea:
eukaryotic organisms have distinct nucleus. Can be uni/multicellular - CORRECT ANSWER✔✔Fungi:
eukaryotic; unicellular. Most are parasites, names means "first animals" - CORRECT ANSWER✔✔
Protozoa:
,uni/multicellular that obtain nourishment through photosynthesis. - CORRECT ANSWER✔✔Algae:
non cellular that are parasites of cells. Structurally simple, difficult to kill. Smaller than bacteria. -
CORRECT ANSWER✔✔Viruses:
Bacteria, Archaea, and Eukarya. - CORRECT ANSWER✔✔All organisms are classified into three basic
domains. What are the domains?
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 - CORRECT ANSWER✔✔
Explain the importance of observations made by Hooke and van Leeuwenhoek.
Spontaneous generation is that life could spontaneously generate
Biogenesis- the theory that living cells can arise only from preexisting living cells. - CORRECT ANSWER✔
✔Compare the theories of spontaneous generation and biogenesis.
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. - CORRECT ANSWER✔✔Identify the
contributions to microbiology made by Needham, Spallanzani, Virchow, and Pasteur.
Proved that microorganisms caused disease - CORRECT ANSWER✔✔Identify the importance of Koch's
postulates.
, 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 - CORRECT ANSWER✔✔Explain
how Pasteur's work influenced Lister and Koch.
He demonstrated that inoculation with cowpox material provided humans with immunity from small
pox - CORRECT ANSWER✔✔Identify the importance of Jenner's work.
Ehrlich introduced an arsenic containing chemical called salvarsan to tx syphilis
Flemming observed that mold (penicillium) inhibited the growth of a bacterial culture. - CORRECT
ANSWER✔✔Identify the contributions to microbiology made by Ehrlich and Fleming.
Bacteriology: the study of bacteria
Mycology: the study of fungi
Parasitology: the study of parasitic protozoa and worms
Immunology: the study of immunity
Virology: study of viruses - CORRECT ANSWER✔✔Define bacteriology, mycology, parasitology,
immunology, and virology.
bacteria can produce substances such as proteins, vaccines, and enzymes - CORRECT ANSWER✔✔
Explain the importance of recombinant DNA technology.
Microorganisms degrade dead plants and animals and recycle chemical elements to be used by living
plants and animals. Bacteria are used to decompose organic matter in sewage, and bioremediation
processes use bacteria to clean up toxic wastes. Bacteria are being used to control insect populations,
and microbes are commonly used to make products such as food and chemicals (called biotechnology). -
CORRECT ANSWER✔✔List at least four beneficial activities of microorganisms.
