The invention of the electron microscope opened up many doors for biologists as it helped them to view and learn the appearance of cells and their sub-cellular structures

<h3>What is an electron microscope?</h3>

Electron microscope are microscopes which helps biologists to view the appearances of cells of organisms which cannot be seen with our nak -ed eyes.

Generally, electron microscopes:

Uses a beam of accelerated electrons as its source of illumination
Helps in obtaining high resolution images of biological and non-biological specimens.
It is also used in biomedical research

In conclusion, electron microscope helps biologists to view, learn and to also understand the appearance of cells and their sub-cellular structures
