Answer

• • Bacteria are single celled organisms which can live on their own outside a host. On the other hand, viruses are neither single-celled nor multi-celled and cannot live on their own without relying on the host.
  • Most bacteria do not cause diseases, but most viruses cause diseases
  • Bacteria has a cell wall while a virus lacks virus a cell and a cell membrane.
  • Bacteria divides by binary fission while virus divides by replicating their genome.

Explanation:
Bacteria are relatively complex, single-celled creatures with rigid wall and membrane surrounding fluid inside the cell.Unlike bacteria, viruses cannot live by their own without a host. Another difference is that no all bacteria cause diseases, but most viruses cause diseases and are specific in cells they attack.
