Cell
The smallest unit of life capable of carrying out all life processe

Rudolf Virchow
The scientist who stated that all cells come from pre-existing cells
Pre-existing Cells
Cells that already exist and divide to produce new cells
Unicellular Organism
An organism made of only one cell
Multicellular Organism
An organism made of many specialized cells
Cell Membrane
A thin flexible barrier that surrounds the cell and controls what enters and leaves
