c. Mid to late 1800s

, d. Mid to late 1900s
ANS: C
Mid to late 1600s and mid to late 1700s were too early. Mid to late 1800s was the time when

5. What microbes are used to make vinegar, vitamins, drain cleaners, enzymes, and other
products?
a. Fungi
b. Viruses
c. Protozoa
d. Bacteria
ANS: D
Fungi can make antibiotics but not these products. Viruses grow inside living cells and do not

7. What microbe is used to make bread dough rise?
a. Bacteria
b. Yeasts
c. Viruses
d. Protozoa
ANS: B
Bacteria do not produce enough carbon dioxide (CO2) to make the dough rise. Yeasts
metabolize carbohydrates to produce the gas bubbles of CO2 which causes the dough to rise.
Viruses only grow inside of living cells and do not have a regular metabolism. Protozoa do not
produce enough carbon dioxide (CO2) to make the dough rise.

bacteriophages

Animal viruses had been previously discovered, so they gave bacterial viruses a different
name – bacteriophages – phage means “to eat.”

3. Microbiology is the study of bacteria, molds, yeasts, protozoa, certain algae, viruses and
_________.

ANS:
archaea

Archaea are single cell microbes morphologically similar to bacteria, but their genes and
metabolic pathways are more closely related to eukaryotes. While they may be present in the
human body, there have been no clear examples of archaeal human pathogens.

TRUE/FALSE

1. The disease of smallpox was involved in the discovery of immunizations in the 1790s by
Edward Jenner.

ANS: T
Edward Jenner is credited with recognizing the concept of immunization when he realized in
the 1790s that milkmaids who caught cowpox, a mild disease, were protected from the more
serious disease of smallpox.

MULTIPLE CHOICE

1. Under what conditions do regular bacteria, excluding Rickettsia and Chlamydia, multiply?
a. In the absence of nutrients
b. Only when they are inside of living cells
c. When they are outside of living cells
d. Only when the temperature is below 7C

ANS: C
Nothing can grow in the absence of nutrients. Rickettsia and Chlamydia are the only bacteria
that can grow inside living cells. Regular bacteria do not need to be inside living cells to grow.
They can obtain their nutrients from the environment. Only the special bacteria called
psychrophiles can grow at these low temperatures.

9. Choose the bacterial structure that controls the flow of nutrients and waste into and out of the
cell?
a. Cell wall
b. Flagellum
c. Cytoplasmic membrane
d. Capsule
ANS: C
The cell wall protects the cell from being crushed. The flagellum provides locomotion. The
cytoplasmic membrane has a function to regulate the entrance and exit of nutrient materials
and waste products. The capsule keeps the cell from drying out and is antiphagocytic.

TOP: CDA, Does not apply

10. Which of the following bacterial structures interferes with phagocytosis?
a. Cell wall
b. Flagellum
c. Cytoplasmic membrane
d. Capsule
ANS: D
The cell wall protects the cell from being crushed. The flagellum provides locomotion. One of
the functions of the cytoplasmic membrane is to regulate the entrance and exit of nutrient
materials and waste products. The capsule’s “slimy” nature interferes with phagocytosis.

11. Which of the following bacterial structures helps the cell to attach to surfaces?
a. Cell wall
b. Capsule
c. Cytoplasmic membrane
d. Fimbriae
ANS: D

, The cell wall protects the cell from being crushed. The capsule keeps the cell from drying out
and is antiphagocytic. One of the functions of the cytoplasmic membrane is to regulate the
entrance and exit of nutrient materials and waste products. Fimbriae serve as mechanisms by
which cells can attach to other cells or other environmental surfaces.

12. The main function of the bacterial cell wall is to
a. protect against drying.
b. protect against crushing.
c. to control the exit of wastes from the cell.
d. provide the cell with locomotion.
ANS: B
Protect against drying is a function of the capsule. The basic components of the cell wall
(peptidoglycan) protect the cell from being crushed. Controlling the flow of nutrients and
waste is a function of the cytoplasmic membrane. Providing the cell with locomotion is a
function of the flagellum.

13. The main function of bacterial fimbriae is to
a. control the exit of wastes from the cell.
b. protect against crushing.
c. allow the cell to attach to surfaces.
d. protect against drying.
ANS: C
Controlling the exit of wastes from the cell is a function of the cytoplasmic membrane.
Protection against crushing is a function of the cell wall. Fimbriae serve as mechanisms by
which cells can attach to other cells or other environmental surfaces. Protection against drying
is a function of the capsule.

14. Choose an environment in which psychrophilic bacteria grow best.
a. In the human body
b. In hot water heaters
c. Anywhere the temperature is 37C
d. In the refrigerator
ANS: D
The human body, hot water, and 37C are all too warm for the growth of psychrophiles. The
refrigerator at 7C provides the optimal grow temperature for psychrophiles.

15. Which of the following groups of bacteria grow best inside your refrigerator?

, a. Psychrophiles
b. Thermophils
c. Mesophils
d. Acidophils
ANS: A
Psychrophiles are “cold-loving” and optimal growth is refrigerator temperature. Thermophils
love high temperatures. Mesophils love medium (e.g., body) temperatures. Acidophils
produce acids and are unrelated to temperature.

16. How would prevent the growth of an obligate anaerobe?
a. Adjust the pH of the environment to 7.0.
b. Remove protein of the environment.
c. Maintain the environmental temperature to 37C.
d. Add oxygen to the environment.
ANS: D
A pH of 7.0 will support the growth of most bacteria. Removing protein will not always
prevent growth. Keeping the temperature at 37C will allow many bacteria to grow. Adding
oxygen to the environment will prevent growth since they require low or no oxygen for
growth.

17. Those bacteria that die in the presence of oxygen are called
a. aerobes.
b. mesophils.
c. acidogens.
d. anaerobes.
ANS: D
Aerobes need oxygen for growth. Mesophils grow at medium temperatures and most are
aerobes. Acidogens produce acids during growth and some are aerobes and some anaerobes.
Anaerobes cannot tolerate oxygen.

18. Acidogenic bacteria are noted for producing large amounts of
a. acids.
b. vitamins.
c. proteins.

Acidogenic bacteria produce large amounts of acid. Vitamins may also be produced but do not
relate to being acidogenic. Proteins and carbohydrates are also produced but do not relate to
being acidogenic.
