Difference Between Virus and Bacteria
Bacteria
- Living/Cellular: Complete living cells that can reproduce independently.
- Reproduction: Binary fission.
- Treatment: Treated with antibiotics.
- Size: Larger (detectable via light microscope).
Viruses
- Non-living/Non-cellular: Genetic material encased in protein; need a host to replicate.
- Reproduction: Replicate using host machinery.
- Treatment: Treated with antivirals; vaccines help prevent infections.
- Size: Much smaller (require electron microscope).
Comparison Table
| Feature | Virus | Bacteria |
|---|---|---|
| Composition | DNA or RNA in protein coat | DNA, Cytoplasm, Organelles |
| Metabolism | Dependent on host | Independent |
| Effect | Always pathogenic/parasitic | Many are beneficial (digestion) |
