AND 100% CORRECT WELL DETAILED
Motility - ANSWER semisolid media shows what?
Isolating/culturing bacteria - ANSWER solid media is best for?
Synthetic; defined - ANSWER What are the terms for a media whose exact chemical
compositions are known?
Differential media - ANSWER allows growth of several types of microbes and displays
visible differences among those microbes
Selective media - ANSWER suppress unwanted microbes and encourage desired
microbes
Reducing media - ANSWER a culture medium containing ingredients that will remove
dissolved oxygen from the medium to allow the growth of anaerobes
Transport media - ANSWER used to maintain and preserve specimens that have to be
held for a period of time before clinical analysis
Assay media - ANSWER used to test the effectiveness of antimicrobial drugs
Enumeration media - ANSWER used by industrial and environmental microbiologists
to count the numbers of organisms in milk, water, food, soil, and other samples

,Inoculation, incubation, isolation, inspection, identification - ANSWER What are the
five I's of microbiology?
Innoculating loop - ANSWER used to transfer bacteria from one place to another
Pure culture - ANSWER a culture containing a single kind of microorganism
Mixed culture - ANSWER microbial culture consisting of two or more species
Dark field - ANSWER What microscope has an image that is brightly illuminated
specimens surrounded by a black field.
Phase-contrast - ANSWER which microscope is used for observing intracellular
structures such as bacterial spores, granules, and organelles, as well as the locomotor
structures of eukaryotic cells such as cilia. (in black-and-white)
Differential interference - ANSWER which microscope provides a detailed view of
unstained, live specimens by manipulating the light. It has additional refinements, including
two prisms that add contrasting colors to the image and two beams of light rather than a
single one.
Conofocal - ANSWER which microscope uses a laser beam of light to scan various
depths in the specimen and deliver a sharp image focusing on just a single plane. It is thus
able to capture a highly focused view at any level, ranging from the surface to the middle of
the cell.
TEM - ANSWER which microscope would be the instruments of choice for viewing the
detailed structure of cells and their organelles and viruses. This microscope produces its
image by transmitting electrons through the specimen.
2
,SEM - ANSWER which microscope bombards the surface of a whole metal-coated
specimen with electrons while scanning back and forth over it. A shower of electrons
deflected from the surface is picked up with great fidelity by a sophisticated detector, and
the electron pattern is displayed as an image on a television screen.
Gram-positive - ANSWER Describing the group of bacteria that have a cell wall that is
structurally less complex and contains more peptidoglycan than the cell wall of gram-
negative bacteria. Stains purple
Gram-negative - ANSWER Describing the group of bacteria that have a cell wall that is
structurally more complex and contains less peptidoglycan than the cell wall of gram-
positive bacteria. Stains pink
Coccus, bacillus, spirillum - ANSWER 3 shapes of bacteria
Spirilla; bacilli; cocci - ANSWER One can generalize that all _______, about half of the
___________, and a small number of ________ have flagella
Gram-negative - ANSWER pilli are only found on _____________ cells
Teichoic acid and lipoteichoic acid - ANSWER function in cell wall maintenance and
enlargement during cell division; move cations across the cell envelope; stimulate a specific
immune response. Gram positive cells walls
Lipopolysaccharide; receptors; endotoxin; negative - ANSWER The uppermost layer of
the OM "sandwich" contains ____________ (LPS). The polysaccharide chains extending off
the surface function as cell markers and ____________. The lipid portion of LPS has been
referred to as ___________ because it stimulates fever and medical shock reactions in gram-
____________ infections such as meningitis and typhoid fever.
Lockjaw; colitis; gas gangrene; botulism - ANSWER What are 4 bacterial endospore
diseases?
3
, Psychophilies - ANSWER cold loving archaea
Thermophiles - ANSWER heat loving archaea
Phagosome - ANSWER vacuole merged with a lysosome
Mitochondria - ANSWER where is the most atp generated?
Cellular movements - ANSWER what is actin filament responsible for?
Maintaining cell structure when cell walls arent present (mitosis) - ANSWER what are
microtubules responsible for?
Structural reinforcement of the cell - ANSWER What are intermediate filaments
responsible for?

Mycelium - ANSWER woven, intertwining mass of hyphae that makes up the body or
colony of a mold is called a __________
Hyphae - ANSWER what are responsible for the fungal reproductive spores
Mycoses - ANSWER fungal infections
