MODULE 1 EXAM
Question 1. True or False: A virus is considered a microorganism.
A. True
B. False
Correct Answer: B. False
Rationale: Viruses are not living and as such are not considered
microorganisms. Viruses can, however, be classified as microbes, a
more general term that includes microorganisms and viruses.
Question 2. What is the smallest biological unit of life?
A. The molecule
B. The cell
C. The atom
,D. The tissue
Correct Answer: B. The cell
Rationale: The cell is the smallest biological unit of life. Molecules
and atoms are not living units, and tissues are composed of multiple
cells.
Question 3. At a generalized level, all cells are comprised of what?
A. Organelles
B. Tissues
C. Macromolecules
D. Organisms
Correct Answer: C. Macromolecules
Rationale: Cells are constructed primarily from macromolecules—
proteins, lipids, nucleic acids, and polysaccharides (carbohydrates).
Question 4. Animalia, Plantae, Fungi, and Protista are all
classifications under what type of organism?
A. Bacteria
,B. Eukarya
C. Archaea
D. Virus
Correct Answer: B. Eukarya
Rationale: Only Eukarya contains animals, plants, fungi, and
protists. Bacteria and Archaea are prokaryotic domains, and viruses
are acellular.
Question 5. True or False: All multicellular microorganisms
classified as Animalia are autotrophic.
A. True
B. False
Correct Answer: B. False
Rationale: Animals are heterotrophic—they obtain energy by
consuming organic compounds. They do not perform photosynthesis
like autotrophs.
Question 6. Microorganisms classified as ______ obtain most of their
energy by converting light energy into chemical energy.
, A. Animalia
B. Fungi
C. Plantae
D. Protista
Correct Answer: C. Plantae
Rationale: Plants (Plantae) are photosynthetic autotrophs that
convert light energy into chemical energy through photosynthesis.
Fungi are heterotrophic, and animals consume organic matter.
Question 7. Define catabolism.
A. The process of building larger molecules from smaller ones
B. The process of breaking down larger molecules into useful energy
sources
C. The process of synthesizing proteins from amino acids
D. The process of copying genetic material
Correct Answer: B. The process of breaking down larger molecules
into useful energy sources
Rationale: Catabolism is the breakdown of complex molecules into
simpler ones, releasing energy that can be used by the cell. This is in
contrast to anabolism, which builds larger molecules.
