- Eukarya
- Bacteria
- Archaea
2
Q
What is the difference between Prokaryotic and Eukaryotic?
A
Eukaryotes have a membrane bound nucleus and Prokaryotes do not.
3
Q
Bacteria
A
- Prokaryotic
- Most are decomposers
- Somae are parasitic
- A few are photosynthetic: Cyanobacteria
- Gram Stain
- On agar, bacteria grow as a colony.
- 3 Shapes
4
Q
Cyanobacteria
A
- Formerly called Blue Green Algae
- Do not have chloroplasts; have thylakoid membranes where photosynthesis happens
- Gloeocapsa
- Oscillatoria
- Anabaena
5
Q
Gloeocapsa
A
- Single cells
- Adhere together because each is surrounded by sticky, gelatinous sheath
6
Q
Oscillatoria
A
- Filamentous cells
- Individual cells resemble tack of pennies
7
Q
Anabaena
A
- Filamentous
- Individual cells are barrel-shaped
8
Q
Gram Positive
A
- A lot of peptidoglycan
- Stains purple
9
Q
Gram Negative
A
- Thin layer of peptidoglycan
- Stains Fushia or Red
10
Q
Colony
A
Contains cells decended from one original cell
