Prokaryotes
Microorganisms that do not have a
nucleus in their cells
Disease causing microorganisms Pathogens
Viruses
Microorganisms composed only of
heredity material wrapped in a
protein covering
Classification
Orderly arrangement of organisms
into a hierarchy of taxonomic
categories
Italicized or underlined
When assigning a scientific name to
an organism, both the genus and
species names are ______ or
______.
The five I's of studying Inoculation, incubation, inspection, isolation, and identification
microorganisms are?
Contains only one species of Pure culture
microorganisms
Agar
An important component of media
because it provides a solid surface
for bacterial growth
Objective lens
Magnifies the specimen to produce
the real image of the specimen
How is total magnification The power of the ocular lens is multiplied by the power of the objective
determined? lens
Two functions of bacterial Attachment and motility
appendages
The presence of flagella all over the Peritrichous
cell surface
Basal body, hook and filament
Prokaryotic flagella has three parts
in the order from cytoplasm to
external environment is?
Plasmids
Often the site of pathogenic genes
A unique macromolecule found in Peptidoglycan
bacterial cell walls

, Fortis Microbiology Final Exam
Prokaryotes
-DNA not encased in a membrane
- has a cell wall made of
peptidoglycans or other distinct
chemicals
- does not have membrane-bound
organelles
- DNA is wrapped around histones
Fimbriae
Short, numerous appendages used by
some bacterial cells for adhering to
surfaces
Protein synthesis would stop
The most immediate result of
destruction of a cell's ribosomes
would be that?
Host cells of viruses include? Humans, other animals, plants, fungi, and bacterial
The core of every virus particle Either DNA or RNA but not both
always contains?
Host cell's bucleus
Where does DNA viruses multiply?
Host cell's cytoplasm
Where does RNA viruses multiply?
Viruses attach to their hosts by way Glycoproteins
of the host's?
Infect Escherichia coli cells? T-even bacteriophages
- isolate and identify viruses I. Clinical specimens
- prepare viruses form vaccines
Primary purpose of viral cultivation - do detailed research on viral structure, lifestyle, genetics, and effects on
is to? host cells
Retroviruses differ from other Consist of RNA that changes to a DNA
viruses in that they?
Required for bacteria because it Calcium
stabilizes the cell wall
Organisms that feed on dead Saprobes
organisms for nutrients
Endocytosis
The use of energy by a cell to
enclose a substance in its membrane
by forming s vacuole and engulfing
the substance
