Cell
Basic unit of life
Eukaryote
Cells that do have a nucleus and membrane bound organelles
Scanning electron microscope
Electron illumination, 3D, high magnification n and resolution, specimen is coated in gold and electrons bounce off to give an exterior view of specimen, back and white

cell theory
1) All cells come from pre existing cells
2) All living organisms are composed of one or more cells
3) Cells are the basic unit of life

Compound microscope
Light illuminated, 2D, most commonly used, high magnification, low resolution, shows individual cells and living cells.

Prokaryote
Cells that do not have a nucleus or membrane bound organelles.
Dissecting microscope
Light illuminated, 3D, cannot see individual cells, low magnification, better look at a larger specimen, used for dissection
