Chapter 11 Flashcards
Morphology of Prok Cells info review
most diverse group of cellular microbes
thrive in various habitats
only a small percentage causes diseases
variety of shapes and characterizations
singlular circle shape name
coccus
looks like 2 circles next to each other
coccobacillus
looks like a rod shape
bacillus
looks like a comma shape almost
vibrio
looks like a clear S or curvy rod shape
Spirillum
A bunhc of little circles in a long line
Spirochete
randomization of shapes name
pleomorphic
Looks like a blob almost shape
star
how are the arrangements of prok cells coming about
in differences in how the cell divide
Long rod by itself arrangement name
single bacillus
Two rods next to each other arragnement name
diplobacilli
a long line of rods next to each other arrangement name
streptobacilli
two circles next to each other arrangement name
diplococci
a long line of circles alligned next to each other arrangement name
streptococci
a group of 4 circles arrangement name
tetrads
a group of 8 circles in an arrangement name
satcinae
a large cluster of circles arrangement names
staphylococci
what produces endospores
g + bacteria, like bacillus and clustridium
what do endospores do
they are a defensive strategy against unfavorable or harsh conditions
are archaea known to cause diesease
no
do archaea have peptidoglycan
no
do archaea have cytoplasmic membranes
yes, all of them
what do cytoplasmic membranes do
control import and export
what are the lipids linked with in the membrane of archaea
ether linked
what is something that extremophiles have
monolayers
halophiles are what
in saline habitats
methanogens are what
the largest group of archaea
what do methanogens do
they convert co2, h2, and organic acids to methane gas
where are methanogens found
like the colons of animals
whats special about extremophiles
they have membranes with ether links instead of ester links
what do deeply branching and phototrophic bacteria do
perform photosynthesis
what are the 5 pigment groups
cyanobacteria (blue-green)
green sulfur
green nonsulfur
purple sulfur
purple nonsulfur
what does cyanobacteria do big picture
perform photosynthesis
what was chloroplasts possibly developed from
cyanobacteria
what turned anaerobic atmosphere to aerobic
cyanobacteria
what do some species of cyanobacteria perform
nitrogen fixation
name some types of gram negative proteobacteria
nitrogen fixers
rhodopseudomonas palustri
clasi betaproteobacteria
sphaerotilus
nitrogen fixers main idea
grow on plant roots,
agriculture are axospirillum and rhizobium
rhodopseudomonas palustria main idea
diverse metabolism
biodegration
h2 production
clasi betaproteobacteria main idea
main type is zoogloea
that forms flocs that assist in the treatment of sewage
floc def
a clumped mass of particles
sphaerotilus main idea
sewage fungus , but is bacterial
flocs impede flow of waste in treatment plants
