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?
