Why are electron microscopes an advantage when studying cells?

Answer 1

What is electron microscope?--Any of a class of microscopes that use electrons rather than visible light to produce magnified images, especially of objects having dimensions smaller than the wavelengths of visible light, with linear magnification approaching or exceeding a million (1,000,000 X).

Modern electron microscopes can magnify objects up to two million times, they are based upon Ruska's prototype and his correlation between wavelength and resolution.

The electron microscope is an integral part of many laboratories. Researchers use it to examine biological materials (such as microorganisms and cells), a variety of large molecules, medical biopsy samples, metals and crystalline structures, and the characteristics of various surfaces.

ANY MICROSCOPE THAT CAN GIVE MAGNIFICATION OF TWO MILLION (2,000,000 x ) WILL BE OF GREAT ADVANTAGE IN ANY STUDY.

Now I think that you are convinced

Answer 2

Electron microscopes have the capability of far greater magnification and resolution than light microscopes. We can see much greater detail of the cells.

Answer 3

They can magnify images to show the structure of the cell membrane and cell organelles. We can actually see the double layer membrane. These microscopes use electron beams instead of light to show the image. The resulting images are much clearer and larger.
