Microscopy Methods

Microscopy has evolved from simple light lenses to advanced electron beams, revealing the smallest sub-cellular structures.

Do you know how to prepare a slide?

What is Microscopy Methods?

"Microscopy is the use of lenses or electron beams to magnify and resolve sub-cellular structures that are too small to be seen with the naked eye."

Question 1

What is the main advantage of an electron microscope over a light microscope?

Question 2

What does higher resolution mean when looking at cells?

Question 3

Which formula is used to calculate magnification?

Question 4

Which formula is used to calculate magnification?

Light vs Electron

Light microscopes are portable and can view live specimens but have limited resolution.

Electron microscopes have much higher magnification and resolution but are expensive and fixed.

Exam Tip

Resolution is the ability to distinguish between two separate points.
