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
