- Features of a prokaryote
- Genetic material (DNA) - Nucleoid genophere
- Circular loop of DNA, not associated with protein
- Carried genetic info-for proteins
- Cell wall
- Made of peptidoglycan
- Prevents osmotic lysis, right & strengthening
- Capsule
- Extra layer outside cell wall
- Prevents from desccication (drying out) and some pathogens
- Cytoplasm
- Solution where many dissolved molecules are
- Site of many metabloc reactions
- Cell surface membrane (plasma membrane)
- Phospholipid bilayer with proteins
- Plasmids
- Small loops of DNA, can replicate independently
- Eg- Can pass on genetic info via conjugation to other species
- Genetic material (DNA) - Nucleoid genophere
- Cell surface membrane (plasma membrane)
- Phospholipid bilayer with proteins
- Selectively permeable
- Plasmids
- Small loops of DNA, can replicate independently
- Eg- Can pass on genetic info via conjugation to other species
- Simple flagella (often present and may be more than one)
- Thin rotating fibre
- Responsible for movement of cell
