I need the same answer!!! What I could find in my book is that unlike the optical microscopes, electron microscopes use a vacuum so there can be no living specimen. So no living specimen is my final answer.
Can not see electrons.

Really small things. Because there are limits to how small an object we can observe through a light microscope, we developed the electron microscope. By setting up a sample and streaming electrons at it to resolve an image, we can "see" things smaller than we'd be able to see through a light microscope.
Ribosomes are very small.So have to use an electron microscope.
Electron microscopes don't have the resolving power to see individual molecules.
You can see parts of cells by microscopy.A light microscope will reveal detail with a resolution down to about 0.2 micrometers. More detail becomes visible using various techniques, such as staining or phase contrast microscopy.An electron microscope improves the resolution to about 2 nanometers. What is seen in an electron micrograph is the shadow left by heavy metal atoms in the stain, which has attached to cell structures.

it enables us human beings to see a world of science we have never been able to see before, its fantastic
This virus has a shape like a soup can. See the link below for a micrograph: Cylindrical shapes: Tobacco mosaic virus Wheat streak virus Hepatitis C

No. No matter how powerful an optical microscope is, it can never be used to see atoms. Atoms are smaller than the wavelength of visible light. You can, however, view atoms using an electron microscope.
A virus of 50nm would be too small to see unless an electron microscope was used because it has greater resolving power and a resolution up to .1nm. A microscope using compound light as the means of illumination could not resolve better than approx. 200nms.
