EVERYDAY SCIENCE

Detailed explanation-1: -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-2: -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-3: -Finally, a virus isn’t considered living because it doesn’t need to consume energy to survive, nor is it able to regulate its own temperature.

Detailed explanation-4: -Viruses are tinier: the largest of them are smaller than the smallest bacteria. All they have is a protein coat and a core of genetic material, either RNA or DNA. Unlike bacteria, viruses can’t survive without a host. They can only reproduce by attaching themselves to cells.

Detailed explanation-5: -Bacteria and Viruses are quite different from each other. Bacteria live in nature whereas Viruses can thrive both in living and nonliving habitats. Bacteria can survive without a host but Viruses will die without a host. Bacteria reproduce through binary fission and Viruses reproduce through lytic fission.
