EVERYDAY SCIENCE

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 100 times smaller than bacteria and can only be seen through the highest form of microscopy. They become easily airborn and this is why viruses often enter the human body through our respiratory systems.

Detailed explanation-3: -COVID-19 Learning Note: Viruses are much smaller than human cells; they’re even smaller than the bacteria in our bodies. Their tiny size makes them too small to see under a light microscope and detectable only by other means.

Detailed explanation-4: -This meant that something even smaller than bacteria was causing the infection. Scientists did not actually see viruses for the first time until the 1930s. That’s when the electron microscope was invented. In 1915, English b acteriologist Frederick Twort discovered bacteriophage, the viruses that attack bacteria.

Detailed explanation-5: -And viruses are smaller again-they’re about a hundredth the size of our cells. So we’re about 100, 000 times bigger than our cells, a million times bigger than bacteria, and 10 million times bigger than your average virus!
