Prokaryotic/Eukaryotic Flashcards
Morhpology
Shape
The three shapes of bacteria are
Round, Rod, Spiral
Round bacteria are called
cocci
Rod bacteria are called
bacilli
What are the three kinds of spiral bacteria?
Vibros, Spirillium and Spirochetes
Cocci are
non motile
bacilli are
motile
Vibros are
comma shaped
spirillium are
s-shaped
spirochetes
true spirals
diplococci
pairs
streptococci
in chains
saphylococci
grapelike clusters
a diplobacilli is found in
pairs and in the environment
streptobacilli
are found in chains
what do most bacilli move by?
flagella
This gelatin layer surrounds the cell wall of bacteria
glycocalyx
If the glycocalyx is thick it is called a
capsule
If the glococalyx is thin it is called a
slime layer
Glococalyx protects bacteria from
dehydration, phagocytosis of eukaryotic cells and chemicals
Virulence
is the degree of severity of disease
a capsule aid is __________ to surfaces
adherance
Two examples of bacteria with capsules are
mycobacterium tuberculosis (Causes TB) and Klebsielle pneumoniae (causes pneumonia)
Flagella
is a bacterial structure that is used to propel bacteria in an aqueous environment
