- Isoprenes instead of fatty acids
- Ether linkages in phospholipid
- Lipid monolayers not biolayers
- Cell structure
- Glycocalyx
- Cytoplasmic membrane
- Ribosomes
- Cell wall
- Nucleoid
- Uptake of nutrients
- Endocytosis (eukarya only)
- Passive diffusion (all)
- Group translocation (not eukarya)
- Facilitated diffusion (all)
- Active transport (all)
- Bacterial cell envelope
- Can act as an endotoxin
- Stabilizes outer membrane structure
- Protection from host defenses
- S layers
- External structures
- Archaeal flagella are thinner
- Flagella for movement
- Pili and fimbriae
- Endospores
- Resting cells
- Resistant to heat, chemicals etc
- Enriched in calcium ions
- Contains dipicolinic acid
- Plasmids
- Exist & replicate independently of chromosome
- Extra-chromosomal DNA
