Cell theory postulates Four statements of the cell theory describing cells’ structure and function. These four observations form the basis of cell biology. They describe cells as 1) the smallest structural and functional unit of life, 2) composing living organisms, 3) being produced by other cells, and 4) responsible for inheritance. At any time, though, new research could challenge these postulates.
