Explanation:

The theory of spontaneous generation was disproven by the cell theory. Cell theory states that all living things are made of cells and cells form from previously existing cells. The statement "All living things are made of cells" shows that life has a cellular basis (not spontaneous from non - living matter). The statement "Cells form from previously existing cells" shows that there is a reproductive mechanism from pre - existing life (contradicting spontaneous generation from non - living matter). The statement "Living cells can only come from previously existing matter" is incorrect as per cell theory (should be from previously existing cells). "Cells are generally microscopic and impossible to detect with the naked eye" is a property of cells but not directly related to disproving spontaneous generation. "All matter is made of cells" is incorrect as non - living matter is not made of cells.

Answer:

All living things are made of cells; Cells form from previously existing cells
