|
|
|
|
Flagella
|
Long Whip like tail
|
|
|
|
How do bacteria accuire energy? (Heterotrophs)
|
Aerobic, anaebrobic or both (known as facultative anaerobic organisms)
|
|
|
|
How do bacteria acquire energy? (autotrophs)
|
Photosythesis- known as blue/green bacterail but it can be almost any color, the red sea has many red bacteria in it
|
Chemosythesis- get energy from inorganic chemicals
|
|
|
Archaebacteria
|
Cell walls DONT have peptidoglycen
|
genes are more like eukaryotic cells believed to be the ancestors of eukayotic cells. they usually live in harsh conditions (high salt, high heat, acidic)
|
|
|
Eubacteria
|
cell walls have peptidoglycen
|
not believed to be the ancestors of eukaryotic cells
|
|
|
Human uses for bacteria

|
produce spores
not-motile (sationary) parasitic |

|
sporozao
|
produce sporesnot motile (staionary) allof these are parascitic
|
|
|
|
sarcodina
|
have pseudopods (false feet) they move by extending part of their cell membrane and cytoplasm
|
|
|
|
what is a representitivespecies of sarcodina
|
ameoboes
|
|
|
|
(plant-like prtoists) Phytoplankton
|
tiny photosythetic organisms at the bottom of the food chain plant like prtists make up half of theses
|
|
|
|
UNicelluar plant like protitss
|
egeoglenopyls
2 falgells no cell wall chlorophyll eyes spot to sense light asexual reproduction |
|

digest decaying matter
|
|
|
|
cellular slime molds
|
remain individual cells their entire existance
lvie on their own buyt when food runs out htey put out a signal, congregate and form a slime colony that movres to a new locations adn releases spores to start the cycle again |
|
|
|
