    The word "Cell/Cells" is created
    This year Robert Hooke created the term cells,he thought of the name while he was looking at a piece cork and called them cells because they reminded him monk cells.

    The Second Microscope
    Anton van Leeuwenhoek discovers bacteria by observing dental scraping, bee mouth parts and stings, a human louse and a fungus, he explains what he found to the Royal Society. He also found protozoa and named in animalcules
  • 2nd Scientist Who Helped Evolve The Cell Theory

    2nd Scientist Who Helped Evolve The Cell Theory
    Karl Rudolphi helped the cell theory by being one of the first people to prove that cells had independent cell walls
  • Confirmation Of Cell Theory

    Confirmation Of Cell Theory
    Robert Remak substantiated the fact that the cell membrane existed that then proved that all cells come from already existing cells. Verifying that Theodor Schwann was correct saying that all cells came from already existing cells
  • The Discovery of Plant Cells

    The Discovery of Plant Cells
    Matthias Schleiden discovered that all plants were also made out of cells, declaring that a cell is the building block of all plant matter.
  • The Discovery of Animal Cells

    The Discovery of Animal Cells
    Theodore Schwann concluded that all animal tissue was made up of cells just like plant cells and that all tissue in general are made up of cells.
  • Conflict With The Cell Theory

    Conflict With The Cell Theory
    Theodor Schwann and Matthias Schleiden disagreed on the 3rd part of the cell theory, where Schleiden believed that cells formed out of crystals by themselves. Schwann believed that cells formed from already existing cells
  • Other Scientist Who Contributed to The Cell Theory

    Other Scientist Who Contributed to The Cell Theory
    Rudolf Virchow helped develop the cell theory and was one of the first to accept the work the Robert Hooke created about the cell theory.
  • Endosymbiotic Theory

    Endosymbiotic Theory
    The Endosymbiotic Theory is the evolutionary theory about how the eukaryotic cells originated from prokaryotic organisms. This theory was created in 1905 by the Russian botanist Konstantin Mereschkowski.
