1675 The Discovery of Plant Cells
Hello, My name is Robert Hooke, I am an English scientist. I'm currently looking at some cork and it appears to have tiny little boxes. I think I'll call them cells because it reminds me of where monks sleep. I use a compound microscope (2 or more lenses).
Over the next 200 Years microscopes and scientific technology improve significantly meaning that microscopes have improved there magnification and complexity.
