|
once, all prokaryotes were placed in -
|
Monera
|
|
|
Now, two different kingdoms (prokaryotes)
|
Eubacteria and Archaebacteria
|
|
|
cell wall protects cell
- determinutes shape - peptioglycon |
eubacteria
|
|
|
eubacteria has a cell membrane that surrounds the -
|
cytoplasm
|
|
|
Eubacteria live in Four places
|
fresh and salt water, on land, in body
|
|
|
- bacteria
has no peptioglycon unique membrane lipids |
archaebacteria
|
|
|
In Archaebacteria, DNA sequence sof key genes are more like - than those of eubacteria
|
eukaryotes
|
|
|
many archabacteria live where?
|
in extreme environments
|
|
|
methanogens live in - environments, such as thick mud and animal digestive tracts
|
oxygen free
|
|
|
salty environments or in hot springs, where water temperature approach boiling point
|
halophiles
|

|
|
positive chemotaxis vs. ___
|
negative chemtaxis
|
|
|
how prokaryotes move. three types
|
flagella,cilla,finbriae
|
|
|
take in organic molecules for both energy and supply of carbon
|
heterotrophs
|
|
|
- use sunlight for energy but take in organic compounds
|
photoheterotrophs
|
|
|
use sunlight to convert carbon dioxide and water to carbon compounds and oxygen
|
photoautotrophs
|
|
|
perform chemosynthesis. they make organic carbon molecules from carbon dioxide, but don't require light as energy
|
chemoautotrophs
|
|
|
require a constant supply of oxygen
|
obligate aerobes
|
|
|
bacteria that live without oxygen because they may be killed by it
|
obligate anaerobes
|
|
|
bacteria that can survive with or without oxygen
|
facultative anaerobes
