Bacteria/Archae Flashcards
obligate anaerobes
poisoned by O2 and use fermentation or anaerobic respiration
Require O2 for celullar respiration
obligate aerobes
Facultative anaerobes
can survive w/ or w/o O2
introduced the three domain system for classification of organisms
Carl Woese
Known as extremophiles and are similar to both prokaryotes and eukaryotes
Archaea
Has allowed for more rapid sequencing of prokaryote genomes
Polymerase chain reaction (PCR)
Nuclear Envelope is found in
neither Bacteria and Archaea
Membrane Bound organelles
Not in Bacteria/Archaea
Peptidoglycan in cell wall
Bacteria only
Ecological relationship where 2 different species live in close contact (host and symbiont)
symbiosis
Function as decomposers (break down corpses)
Chemoheterotrophic prokaryotes
both symbiotic organisms benefit
mutualism
one organism benefits while neither harming nor helping the other
commensalism
parasitism
harms but not kills the host.
Parasites that cause diseases
pathogens
cause disease even if prokaryote is not present
exotoxin
released when bacteria die and cell wall breaks down
endotoxin
Prokaryotes are the principle agents in ______
Bioremediation
The use of organisms to remove pollutants from the environment
bioremediation
How do bacteria resist antibiotics?
R plasmids carry antibiotic resistant genes
Piece of DNA that is required for sex pili production
