Tholen, UTA Microbiology exam 1 (ch 1,2,3,7) Questions
With Complete Solutions
(T/F) all bacteria require nutrients in order to survive. Correct
Answers True. Some do this via photosynthesis or from other
organic/nonorganic compounds.
(T/F) within 1 species of a microorganism, there can be several
subtypes called strains. Correct Answers True, can be nearly
identical genetically. Every strain varies in ability to cause
disease.
Agar Correct Answers a gel-like polysaccharide compound
used for culturing microbes; extracted from certain red algae.
Algae Correct Answers Can be uni- or multicellular,
eukaryotic, cellulose wall
Antoine van Leeuwenhoek Correct Answers Father of
microbiology. Invented a microscope strong enough to view
microbes "animalcules".
Archaea Correct Answers Domain of unicellular prokaryotes
that have cell walls that do not contain peptidoglycan (have
pseudo-peptidoglycan). Can survive in extreme environments
unlike bacteria.
At what size is a object visible to the naked eye? Correct
Answers About 10 um
Bacillus Correct Answers rod-shaped bacterium
, Bacteria Correct Answers Unicellular, prokaryotic,
peptidoglycan wall (not all), some capable of photosynthesis
Bergey's Manual of Bacteriology Correct Answers Manual for
identifying and classifying microorganisms via non-visual
characteristics.
Binomial nomenclature Correct Answers Classification system
in which each species is assigned a two-part scientific name.
(Written in italics, Genus is capitalized, species lower case)
Carl Woese and George Fox Correct Answers Studied the
small subunit of the ribosome
Proposed a separate taxonomic unit: Archaea.
Also proposed a new taxonomic system representing three
domains: bacteria, archaea, and eukarya.
Carolus Linneaus Correct Answers The "Father of
Taxonomy". He came up with our modern day system of
classification called Binomial Nomenclature. Most famous early
taxonomists. Divided 3 kingdoms animal, plant, and mineral.
Sublevels: kingdom, class, order, family, genus, species
Cilia Correct Answers Hairlike projections that extend from
the plasma membrane and are used for locomotion.
Coccobacillus Correct Answers A short round rod shaped
bacterium
Coccus Correct Answers A spherical bacterium.
