List several ways in which microbes affect our lives. -
Answer-· Maintenance of an ecological balance on earth
Produce foods and chemical necessary for the survival of
humans
Maintain health present on your skin, in your mouth, and
in your stomach
Recognize the system of scientific nomenclature that uses
genus and specific epithet names. - 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. - Answer-Most common shapes
of bacteria: Bacillius (rodlike); Coccus (spherical or ovoid);
spiral (corkscrew or curved).

Archaea: - Answer-consist of prokaryotic cells and don't
have cell walls. They live in extreme environments
Fungi: - Answer-eukaryotic organisms have distinct
nucleus. Can be uni/multicellular
Protozoa: - Answer-eukaryotic; unicellular. Most are
parasites, names means "first animals"
Algae: - Answer-uni/multicellular that obtain nourishment
through photosynthesis.
Viruses: - 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? - Answer-Bacteria, Archaea, and
Eukarya.
Explain the importance of observations made by Hooke
and van Leeuwenhoek. - Answer-Hooke discovery marked
,3|Page
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. - 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. - 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. - Answer-
Proved that microorganisms caused disease
, 4|Page
Explain how Pasteur's work influenced Lister and Koch. -
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. - 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. - Answer-Ehrlich introduced an arsenic
containing chemical called salvarsan to tx syphilis
Flemming observed that mold (penicillium) inhibited the
growth of a bacterial culture.
Define bacteriology, mycology, parasitology, immunology,
and virology. - Answer-Bacteriology: the study of bacteria
Mycology: the study of fungi
Parasitology: the study of parasitic protozoa and worms
