WebCan light microscope see viruses? Standard light microscopes allow us to see our cells clearly. However, these microscopes are limited by light itself as they cannot show anything smaller than half the wavelength of visible light and viruses are much smaller than this. But we can use microscopes to see the damage viruses do to our cells.
WebDec 28, 2024 · Viruses can be seen as obligate, intracellular parasites. A virus must attach to a living cell, be taken inside, manufacture its proteins and copy its genome, and find a way to escape the cell so that the virus can infect other cells.
