1. When humans manipulate the genes of microorganisms,
the process is called ______.
a. bioremediation
b. genetic engineering
c. epidemiology
d. immunology
e. taxonomy
Correct Answer: b
Rationale: Genetic engineering is the direct manipulation of an
organism's genes using biotechnology. The other options refer to
,Page 2 of 153
different branches or applications of microbiology. (Section
01.01; Bloom's: Remember)
2. Which of the following is NOT considered a
microorganism?
a. Mosquito
b. Protozoan
c. Bacterium
d. Virus
e. Fungus
Correct Answer: a
Rationale: Microorganisms are microscopic organisms, including
bacteria, archaea, protozoa, fungi, helminths, and viruses. A
mosquito is a macroscopic insect visible to the naked eye.
(Section 01.01)
3. All microorganisms are best defined as organisms that
______.
,Page 3 of 153
a. cause human disease
b. lack a cell nucleus
c. are infectious particles
d. are too small to be seen with the unaided eye
e. can only be found growing in laboratories
Correct Answer: d
Rationale: Microorganisms are living things ordinarily too small
to be seen without magnification. Some are beneficial, not all
lack a nucleus (eukaryotes do), and they exist widely in nature.
(Section 01.01)
4. The Dutch merchant who made and used quality
magnifying lenses to see and record microorganisms was
______.
a. Louis Pasteur
b. Francesco Redi
c. Antonie van Leeuwenhoek

d. Robert Koch
e. Joseph Lister
Correct Answer: c
Rationale: Antonie van Leeuwenhoek is known as the "Father of
Microbiology" for his pioneering work with microscopes and his
discovery of "animalcules" (microorganisms). (Bloom's: Remember)
5. Which of the following is a role played by microorganisms
in our environment?
a. Carry out photosynthesis
b. Biological decomposition
c. Nutrient recycling
d. Complex relationships with animals but not plants
e. All of the above
Correct Answer: e
Rationale: Microorganisms perform essential ecosystem services
including photosynthesis (e.g., cyanobacteria), decomposition
