Cell Theory (1983, Schuman)

1) All living organisms are made up of one or more living

cell(s)

2) Each cell maintain its living properties independently

but organism life is based on each cell properties.

3) The smallest clearly defined unit of life is the cell.

4) Cells arise only from other cells.
