Before Anton van leeuwenkoek people thought what diseases for caused by curses.
Robert hook at around that same time as Anton studied cells with a compound light microscope.
If I'm to forget all about cells i at least need to remember the cell theory
1) All organisms are made up of cells
2) The cell is the basic unit of organisms
3) All cells come form preexisting cells
The electron microscope is only about 61 years old its hard to believe it has been around that long.
the two kinds of electron microscopes SEM and TEM.
I want to know more about how hey react to each other ?
