The Cell: Seeing the Invisible

The video explains the importance of cells and their visibility through microscopes. It covers the evolution of microscopes from single-lens to compound light microscopes, which magnify objects up to 1000 times. For greater magnification, electron microscopes are used, capable of magnifying up to 1,000,000 times. These microscopes use magnetic fields to bend electron beams and are used to study the surface of objects.

What is the significance of magnification in microscopy?

Explain how a scanning electron microscope differs from other types of electron microscopes.
