2 kingdoms:
-
Eubacteria – do not have cell walls
o Producers
o Decomposers
-
Archaebacteria – have cell walls
o Heat Lovers
o Salt Lovers
o Methane Makers
3 Shapes
1. Bacilli
2. Spirilla
3. Cocci
Flagella
Hairlike parts that help bacteria move.
Prokaryote
An organism that consists of a single cell and does NOT have a nucleus.
Ekaryote
An organism that consists of a single cell and does have a nucleus.
Binary Fission
A form of reproduction when a single celled organism splits into two
single celled organisms.
Steps of Binary Fission:
1. Cell Grows
2. DNA Copies
3. DNA Separates
4. Cell Separates
Endospore
Contains genetic material and proteins. Covered by a thick,
protective coat.
