- using microscopes to look at cells
- it is not possible to see cells as separate objects using the naked eye
- the ability to see two or more objects as separate objects is called resolution
- the light microscope was developed in the late 16th century and gave a greater resolution than the human eye
- it allowed scientist to see plant, animal and bacterial cells
- some sub-cellular structures are even smaller than the resolution achieved by a light microscope and cannot be seen using this method
- in 1933 scientists first used an electron microscope
- an electron microscope passes electrons rather than light through the specimen and can give much better resolution
- cells can be seen in much finer detail
