Transcript of Kingdoms Eubacteria and Archeabacteria · Type of Archaebacteria Characteristics Where they can be...
Kingdom Eubacteria
◦True bacteria
◦Unicellular prokaryotes (no nucleus)
◦Heterotrophic or autotrophic (chemosynthesis and
photosynthesis)
◦Have a cell wall
Harmful vs. Helpful Bacteria
Harmful Bacteria Helpful Bacteria
Cause diseases such as: staph
infection, strep throat, cholera,
tetanus, tuberculosis, and
bubonic plague
Help animals digest food
Cause tooth decay and gum disease Break down dead things
Can destroy roads and pipelines Make oxygen (cyanobacteria)
Spoils food Create food: yogurt, cheese, sour
cream, pickles, soy sauce and
sourdough bread.
Bacterial Reproduction
◦Reproduce asexually
through binary fission
◦ One cell splits to become two
cells
◦Sometimes one bacterial
cell will exchange DNA
with another through
conjugation
Kingdom Archaebacteria
◦ Unicellular, Prokaryotic
◦ Archaebacteria = ancient bacteria
◦ Autotrophic (chemosynthesis) or heterotrophic
◦ Many are extremophiles = lovers of extreme conditions
◦ Most have cell walls
◦ Archaebacteria are more similar to eukarya than eubacteria
Types of Archaebacteria
Type of Archaebacteria Characteristics Where they can be found
MethanogensConvert H2 and CO2
into CH4
Anaerobic environments
(deep fresh water, marine
mud, swamp mud, sewage)
Halophiles Salt loving Great Salt Lake and Dead
Sea
Thermoacidophiles
thrive in hot acidic
places (230 F and pH
> 2)
Hydrothermal vents, volcanic
vents
