A biologist needs to distinguish individual ribosomes in cells from the gills of a fish. The laboratory has a light microscope and an electron microscope.
Which choice gives the microscope that should be used and the reason?
A light microscope, because staining makes ribosomes visible.
An electron microscope, because it has a higher resolution.
An electron microscope, because it can view living cells.
A light microscope, because it has a higher resolution.
