of the cell
Acid-fast cell walls are present in what Correct Answers
mycobacterium
Animals use what and produce what? Correct Answers use O2
and produce CO2
Bacteria contains what> Correct Answers peptidoglycan in their
cell walls
bacterial cells utilize their flagella for movement through a
process called?? Correct Answers running and tumbling
Carolus Linnaeus Correct Answers Father of taxonomy
Characteristics of endospores Correct Answers - highly durable,
withstand dehydration, and have very thick walls, stable for
many years
Characteristics of protozoa? Correct Answers classified by their
method of locomotion, unicellular and all of them are eukaryotic
Consider a gram-positive cell in a hypertonic solution. If the
peptidoglycan were damaged, what would happen to the cell?
Correct Answers The cell would shrink or crenate
,define a biofilm Correct Answers a thin, slimy film of bacteria
that adheres to a solid surface.
Define a compound microscope Correct Answers a microscope
that uses a series of lenses to magnify the image.
define a cytoskeleton Correct Answers made up of
microfilaments, intermediate filaments and microtubules.
Resides in a eukaryotic cell
define a light microscope Correct Answers (LM) an optical
instrument with lenses that refract (bend) visible light to
magnify images and project them into a viewer's eye or onto
photographic film
define a nucleoid Correct Answers contains the bacterial
chromosome
define a prion Correct Answers proteins that are infectious
define a virus Correct Answers needs a host to live. Does not
have metabolism and cannot replicate without a host
Define acid stain Correct Answers an example of differential
staining. It's important in diagnosing mycobacterial infections.
define acid-fast cell walls Correct Answers they have mycolic
acid
, define algae Correct Answers they can make their own sugar
using carbon from the air and energy from sunlight. They live in
wet environments
Define amphitrichous Correct Answers flagella at both ends of
the cell
Define an antibiotic Correct Answers chemicals produced by
bacteria and fungi that inhibit or kill other microbes
define animalia kingdom Correct Answers includes sponges,
worms, insects, and animals with backbones. they obtain
nutrients and energy by ingesting organic matter from others and
through a mouth.
define archaea Correct Answers does not have peptidoglycan in
their cell walls. They live in very extreme environments
define archaea when it comes to atypical cell walls Correct
Answers some bacteria in this domain have cell walls made up
of polysaccharides and proteins but not peptidoglycan
Define aseptic technique Correct Answers Methods and
procedures used in the laboratory to prevent contamination of
the work area, the worker and the cultures with microorganisms.
Define Atrichous Correct Answers no flagella
Define atypical cell walls Correct Answers some prokaryotic
cells have no cell wall or little cell wall material
