Detailed explanation-1: -Viruses are even smaller than bacteria. They aren’t even a full cell. They are simply genetic material (DNA or RNA) packaged inside of a protein coating.
Detailed explanation-2: -Viruses are 10 to 50 times smaller than the smallest bacteria. Bacteria are smaller than protozoans and fungi are the largest microorganisms.
Detailed explanation-3: -Hence, Fungi are generally bigger in size than bacteria.
Detailed explanation-4: -Viruses are the smallest of all the microbes. They are said to be so small that 500 million rhinoviruses (which cause the common cold) could fit on to the head of a pin. They are unique because they are only alive and able to multiply inside the cells of other living things.
Detailed explanation-5: -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.
