Detailed explanation-1: -A virus is not a living organism and can only grow and reproduce in the cells of a host. Bacteria, by contrast, are single-celled organisms that produce their own energy and can reproduce on their own. While both can cause disease, bacteria also serve other vital and healthful roles in nature.
Detailed explanation-2: -On a biological level, the main difference is that bacteria are free-living cells that can live inside or outside a body, while viruses are a non-living collection of molecules that need a host to survive.
Detailed explanation-3: -Key facts. Bacteria are single cells that can survive on their own, inside or outside the body. Viruses cause infections by entering and multiplying inside the host’s healthy cells. It can be difficult to know what causes an infection, because viral and bacterial infections can cause similar symptoms.
Detailed explanation-4: -Bacteria are single-celled, living organisms. They have a cell wall and all the components necessary to survive and reproduce, although some may derive energy from other sources. Viruses are not considered to be “living” because they require a host cell to survive long-term, for energy, and to reproduce.
