Cell Discovery and Theory
Basic Cell Types
Eukaryotic Cells
Have a true nucleus
Multicellular
Membrane-bound organelles
Larger than prokaryotes
Prokaryotic Cells
No true nucleus
Unicellular
Simple cells with no specialized structures
No membrane bound organelles
All cells have a plasma membrane
Microscopes
Elecyron microscopes
Compound light microscopes
Cell Theory:
Cells are the basic structure of all living organisms
Cells arise from only previously existing cels
All organisms are composed of one or more cells
