WGU D311: Microbiology with Lab:
Section 1 QUESTIONS AND ANSWERS
Describes prokaryotic cells. - -Prokaryotic cells are found in coccus form in
both pairs and clusters.
-Describes eukaryotic cells. - -The nuclei of eukaryotic cells are surrounded
by complex nuclear membranes.
-Describe eukaryotic flagella. - -Eukaryotic flagella are flexible, whip-like
structures.
-Describe the endomembrane system. - -It includes the Golgi apparatus,
lysosomes, and vesicles.
-Describe similarities between protozoa and fungi. - -Both can be harmful or
harmless depending on the context.
-Why are algae considered photosynthetic organisms? - -Algae produce
chemical energy from the sun's light energy.
-Why are plasmids important to the survival of organisms? - -Plasmids carry
genetic material, apart from the genome, that can benefit the organism.
-Describe bacteria. - -Some bacteria have cell walls composed of mycolic
acid.
-Which aspect of nutrient cycling is performed only by prokaryotes? - -
Nitrogen fixation
-Which microbial process is useful in the production of alcoholic beverages? -
-Glucose fermentation
-How does microbial bioremediation benefit the environment? - -By helping
to metabolize and remove pollutants in the atmosphere.
-How is penicillin classified? - -As a natural antibiotic
-What describes the relationship of pathogens to virulence? - -Highly virulent
pathogens almost always lead to a disease state when introduced to the
body.
