No significant development in microscope world for about 100 years. Microscope resolution: electron microscope < light microscope < unaided eye. Theodor schwann (zoologist) - proposed cell theory, recognition of structural similarities between animal and plant cells. The cell is the basic unit of structure for all organisms. Fact - something that is true, and something that we can observe or we have observed o. Scientific fact - the attempt to state our best current understanding. This can change until replaced with a better understanding. Make observations -> hypothesis -> make predictions based on your hypothesis -> carry out controlled experiment -> interpret your results to see if they support your hypothesis. Theory - a hypothesis that has been tested critically.
