Bacteria Flashcards
part of diversity unit.
What are the two kingdoms of bacteria?
Eubacteria and Archaebacteria.
What is Archaebacteria.
Archaebacteria is a group of bacteria that thrive under extreme thermo conditions.
What are the three types of archaebacteria?
Thermophiles (live in extremely hot environments like hot springs), Methanogens which grow on CO2 and H2 to produce Methane (in intestines of mammals) and Halophiles (live in extremely salty areas like salt flats).
What’s a bacteria that’s aerobic?
TB (tuberculosis bacterium).
it needs oxygen to survive.
What’s a bacteria that’s anaerobic?
Tetanus and Botulism (the latter affects the nervous system).
they do NOT need oxygen to survive.
Example of a bacteria can live with either/or?
E.coli (everyone’s favorite toilet flu -_-)
Autotroph?
Autotroph(s) are basically organisms that can self sustain either by photosynthesis or chemisynthetic reactions.
Heterotroph?
Heterotrophs are organisms that cannot create their own food and self-sustain (practically every mammal).
What are the four phases of bacterial growth (in order)?
Lag phase (adaptation to environment), Exponential growth phase (y=2^x), Stable phase (stagnant growth due to ‘prefect’ conditions) and Death (running out of supplies and possible immune response).
What are the three possible shapes for Eubacteria?
Coccus- (a ball), Baccilus (a pill) and Spirillium (A spring basically).
What are the three possible Configurations for a Eubacteria?
Staphylo- (A cluster), Diplo- (two balls) and Strepto- (A chain)
