Cell theory was given by Theodor Schwann, Mathias Schleiden and Rudoplh Virchow. The cell theory states :
(i) All living organisms are composed of cells. They may be unicellular or multicellular.
(ii) The cell is the basic unit of life.
(iii) Cells arise from pre-existing cells.
The modem version of the cell theory includes the ideas:
1. Energy flow occurs within the cells.
2. Hereditary information (DNA) is passed on from cell to cell.
3. All cells have the same basic chemical composition.
