Divide by a complex, well-organized mitotic process Liver Cell 9,400x.
B) A black smoker chimney in the deep sea emits iron sulfides at very high temperatures (270 to 380 degrees C). And, these prokaryotes exhibit unique structural or biochemical attributes which adapt them to their particular habitats.īacteria in the Environment example: Iron utilizing Baceria B A A) An acid hot spring in Yellowstone is rich in iron and sulfur. All archaea have features that distinguish them from Bacteria (i.e., no murein in cell wall, ether-linked membrane lipids, etc.).
Live in extreme environments: high salt, high temps Īrchaea = Extremophiles Methanogens (prokaryotes that produce methane) Extreme halophiles (prokaryotes that live at very high concentrations of salt (NaCl) Extreme (hyper) thermophiles (prokaryotes that live at very high temperatures).
