Multiple choice
1. To survive, microbial inhabitants have learned to adapt by varying all of the following, except
A. Growth rate.
B. Growth in all atmospheric2conditions.
C. Growth at particular temperatures.
D. Bacterial shape.
Ans:>d
The chapter begins by discussing the way microbial inhabitants have had to evolve to survivein many
different niches and habitats. It discusses slow growers, rapid growers, and replication wi th scarce or
abundant nutrients, under different atmospheric conditions, temperature requireme nts, and cell
structure. Bacterial shape as a form of evolution is not discussed.
Obj: level 2: interpretation
2. Who was considered the father of protozoology and bacteriology?
A. Anton van leeuwenhoek
B. Louis pasteur
C. Carl landsteiner
D. Michael douglas
Ans:>a
The book discusses anton van leeuwenhoek as the inventor of the microscope and the first perso n to
see the ―beasties.‖ so they dubbed him the father of protozoology and bacteriology.the ot her three
individuals were not discussed.
Obj: level 1: recall
3. Prokaryotic cells have which of the following structures in their cytoplasm?
A. Golgi apparatus
,5
B. Ribosomes
C. Mitochondria
D. Endoplasmic reticulum
Ans:>b
All the structures listed are found in eukaryotic cells, but ribosomes are the only ones thatap ply to
prokaryotic cells.
Obj: level 1: recall
4. This form of dna2is2commonly found in eukaryotic cells.
A. Linear
B. Circular
C. Plasmid
D. Colloid
.
.
Ans:>a
Circular and plasmid dna are usually found only in bacteria, not2eukaryotic cells. Colloid isa pr operty of
protein molecules and is not2associated with nucleotides.
Obj: level 1: recall
5. The nuclear membrane in prokaryotes is
A. Missing.
B. Impenetrable.
C. A classic membrane.
, 6
D. A lipid bilayer membrane.
Ans:>a
Prokaryotic cells do not have any membrane-
Bound structures in the cytoplasm including astructured nucleus.
Obj: level 1: recall
6. A microorganism that is a unicellular organism and lacks a nuclear membrane and truenu cleus
belongs to which classification?
A. Fungi
B. Bacteria
C. Algae
D. Parasite
Ans:>b
Fungi, algae, and parasites are unicellular eukaryotic organisms that contain a true nucleus.b acteria are
prokaryotic and do not contain a true nucleus or nuclear membrane.
Obj: level 1: recall
7. In the laboratory,2the clinical microbiologist is responsible for all the following, except
A. Isolating microorganisms.
B. Selecting treatment for patients.
C. Identifying microorganisms.
D. Analyzing bacteria that cause disease.
Ans:>b
Clinical microbiologists do not select the treatment for patients. They provide the doctor withthe name
of the organism and the antibiotics that can kill the bacteria, but not in the final selection of treatment
protocols.
Obj: level 2: recall
8. What enables2the microbiologist to select the correct media for primary culture and optimizeth
e chance of isolating a pathogenic organism?
