Make up the larger of the two prokaryote kingdoms
Generally are surrounded by a cell wall composed of complex carbohydrates
Contain membranes that carry out the process of photosynthesis
Do not contain the same type of chloroplasts as plants do
This bluish-greenish algae can be found nearly everywhere on earth.
Can survive in extremely hot environments and even extremely cold environment
Lack important carbohydrate found in cell walls
Have different lipids in their cell membrane
Different types of ribosomes
Very different gene sequences
Archaebacteria can live in extremely harsh environments
They do not require oxygen and can live in extremely salty environments as well as extremely hot environments.
Cocci~ Sphere shaped bacteria
Bacillus~ Rod shaped bacteria
Spirrillium ~ Spiral shaped bacteria
Flagella~ Leg-like structures that help to propel the bacterium.
Gram + and Gram – Bacterium Cell Walls
Chemical nature of a cell wall can be determined by Gram Staining
By finding out what color the cell produces when it is gram stained you can figure out the type of carbohydrates in the cell wall
Flagella ~ Tail like structure the whips around to propel the bacterium
Cillia ~ Miniature flagella surround the cell that help to “swim”
Non motile ~ Sticky cillia like structures that keep the bacterium from moving
