1. Compound Light Microscope

2. How does it work? 1.Uses Light and lenses 2.Most common type in schools 3.Can magnify up to 2000x the actual size

3. Pros and Cons Observe living things Observe cellular processes like cytoplasmic streaming, cilia beating Limited magnification Limit of resolution What is the solution for the disadvantages?

4. Electron Microscope TEM – Greater magnification – High resolving power – Beam of electrons pass through specimen SEM – Greater magnification – High resolving power – Beam of electrons hit & bounce off specimen What direct the direction of movement of electrons to create an image?
