Microbiology Module 1 Exam Questions and
Answers with Verified Solutions | Latest
Updated 2026
define microbe an organism or virus too small to be seen
without a
microscope
- microorganisms and viruses
define pathogen a microbe capable of causing death
T/F: all pathogens are microbes true
but
not all microbes are pathogens
divisions of microbiology basic research, process centered, applied
(medical- what were studying!)
What is microbiology? the study of biological processes at the
micro level
viruses are not considered a ___ microorganism
organism - since theyre not living
,what is a cell? small, membrane enclosed unit of life built
with
macromolecules that retains each
characteristic of
life: responsiveness, growth and
reproduction,
metabolism, homeostasis, and
organization
diversity of cells different shapes, sizes, nutritional
requirements,
aerobic or anaerobic, movement, behavior,
etc.
uniformity of cells - built by same macromolecules and use
the
central dogma of biology (DNA --> RNA -->
proteins)
- all cells are related because they
descend from a
previous cell
- genes and their expression guide cellular
activities and have mechanisms for
mutation
types of cells tree see image
, prokaryotic cells Small, simple, no nucleus, no
membrane-bound
organelles, single loop of DNA (circular
plasmids;
nucleosome), no cellulose, cytoplasm, cell
membrane, cell wall (made of carbs),
somtimes
have cilia or flagella (movement)
prokaryotic cells much smaller than
eukaryotic
most abundant
bacteria and archaeas
similarities between prokaryotic - macromolecules (carbs, proteins, lipids,
cells etc.)
and eukaryotic cells - plasma membrane
- cytosol
- chromosomes
- ribosomes
- unicellular
eukaryotic cells - large and complex
- single and multicellular
- plant, animal, and fungal
- DNA stored in nucleus
- specialized organelles
prokaryotic cells are unicellular, virulence (pathologic)
highly diversified group of cells
with
features that can cause -
what size are prokaryotic cells 2-10 micrometers in length
