In 1858, Rudolf Virchow researched and built upon the theories of Schleiden and Schwann. It was he who proposed the theory that all living cells must rise from pre-existing cells.
The modern version of the cell theory includes the ideas that: Energy flow occurs within cells. Heredity information is passed on from cell to cell. All cells have the same basic chemical composition. Opposing concepts in cell theory: history and background. The cell was first discovered by Robert Hooke in 1665 using a microscope. The first cell theory is credited to the work of Theodor Schwann and Matthias Jakob Schleiden in the 1830s. In this theory the internal contents of cells were called protoplasm and described as a jelly-like substance, sometimes called living jelly.
