  2. Viruses are smaller in size (20-400 nm) when compared with bacteria (1000 nm).
  3. Viruses do not have a cell wall but a protein coat is present, while bacteria have a cell wall that is composed of peptidoglycan.
  4. Viruses require a living cell to reproduce, while bacteria can reproduce by itself.
  5. The DNA or RNA of viruses is enclosed inside a coat of protein, while that of bacteria floats freely in the cytoplasm within the cell.
