- Bacteria vs Viruses (structural differences)
- Bacteria
- Average diameter - 0.5-5 micrometers
- Do not have:
- a nucleus
- membrane-bound organelles
- spindle fibre formation during cell division
- In the cytoplasm (inside the cell surface membrane)
- Circular DNA
- Plasmids
- Ribosomes
- protein synthesis occurs freely in cytoplasm
- Mesosomes
- Infolding of the CSM - site of cell respiration
- Out of the cytoplasm
- Cell surface membrane
- Cell wall
- Made of peptidoglycan - NOT CELLULOSE
- Flagellum
- For motility
- Pilus
- Protein tubes allowing for attachment to surfaces and other cells
- Capsule
- Prevents dehydration and allows to form colonies
- Viruses
- Diameters range from 10-300 nanometers
- (far smaller than bacteria)
- Basic structure entails:
- Nucleic strand (RNA or DNA)
- Protein coat
- require a host to reproduce
- Disrupts infected cell biochemistry
- The lysis of infected cells spreads the virus to neighbouring cells
- this process vauses the disease symptoms of the virus
- Diameters range from 10-300 nanometers
- Bacteria
