Spirilla (spiral)
Vibrios (curve)
What are the 2 classification of bacteria when using gram staining?
Gram-positive
Gram-negative
What are the classification of bacteria based on their response to oxygen?
- Aerobic
- Anaerobic
- Facultative Anaerobes
In obtaining energy what are the classification of bacteria?
Heterotrophs
Autotrophs
Bacteria that consume other organisms?
Heterotrophs
Bacteria that feast on decaying organic matter
Saprophyte
Bacteria that makes their own food, using the energy that came from the sunlight and converting it to chemical energy
Autotrophs or Chemoautotrophs
