THE DISCOVERY OF CELLSTHE DISCOVERY OF CELLS
Discovered the first microscope (simple light microscope)
Compound light microscope - uses more than one lens - mainly used today by us
THE DISCOVERY OF CELLSTHE DISCOVERY OF CELLS
Discovered the first CELL
- in cork (dead cells)- named cells for the rooms monks live in
THE DISCOVERY OF CELLSTHE DISCOVERY OF CELLS
Discovered the first CELL

1)1) All organisms are composed of one or All organisms are composed of one or more cellsmore cells
2)2) A cell is a basic unit of organization A cell is a basic unit of organization of all organismsof all organisms
3)3) All cells come from pre-existing cellsAll cells come from pre-existing cells
