BIOD 171 MICROBIOLOGY MODULE 6
COMPLETE STUDY GUIDE WITH SOLVED
QUESTIONS
◉ True of False: The genetic material within a prokaryotic cell is
contained within a membrane-enclosed region.
Answer: False
◉ How many carbon atoms are present in the monosaccharide
glucose?
Answer: 6
◉ Describe the 4 basic bacterial morphologies.
Answer: Coccus (round/spherical), bacillus (rod), vibrio (curved
rod) or spirillum (spiral/corkscrew).
◉ True or False: Archaea, a eukaryotic class of microorganisms, is
capable of surviving harsh environments.
Answer: False
◉ Which of the following microorganisms are considered to be
Eukarya? Select all that apply.
,Animalia
Plantae
Fungi
Protista
Answer: All of them
◉ Microorganisms classified as _________ obtain most of their energy
by converting light energy into chemical energy.
Answer: Plantae
◉ A defining characteristic of fungi is the presence of chitin in the
cell walls. Which of following also contain chitin? Select all that
apply.
A. Mushrooms
B. Bacteria
C. Yeast
D. Molds
Answer: A, C, D
◉ True or False: Protista retain a unicellular classification, as they
are unable to form tissue layers.
Answer: True
,◉ True of False. All multicellular microorganisms classified as
Animalia are heterotrophic
Answer: True
◉ The function of the lysosome is (select all that apply):
A. Lipid synthesis
B. Protein synthesis
C. To produce energy (ATP)
D. Protein modification and distribution
E. Waste disposal via hydrolytic enzymes
Answer: E
◉ The function of the mitochondria is (select all that apply):
A. Lipid synthesis
B. Protein synthesis
C. To produce energy (ATP)
D. Protein modification and distribution
E. Waste disposal via hydrolytic enzymes
Answer: C
◉ The combination of the cell membrane and the outer membrane is
referred to as the (select all that apply):
, A. Cell wall
B. Capsid
C. Cell envelope
D. Outer leaflet
Answer: C
◉ What is the smallest biological unit of life?
Answer: Cell
◉ Define an essential amino acid.
Answer: An essential amino acid cannot be produced by the human
body and as such must be take in from the environment through
alternative sources (i.e) food.
◉ Where can the two major types of nucleic acids be found in the
cell and what are their roles?
Answer: While both DNA and RNA can be found in the nucleus
(center of the cell), only RNA is capable of leaving the nucleus. DNA
contains a vast amount of hereditary information and is responsible
for the inheritable characteristics of living organisms. RNA is
responsible for deciphering the hereditary information in DNA and
using it to synthesize proteins.
