Cell Theory

  • The First Microscope

    The First Microscope
    This the first microscope invented in 1959. Hans and Zacharias Janssen made the first microscope by placing two lenses in a tube.
  • Robert Hooke

    Robert Hooke
    Robert Hooke had studied a thin piece of a cork, and found that there were cells. (pores)
  • Antony van Leeuwenhoek

    Antony van Leeuwenhoek
    He invented the single-lens microscope.
  • Theodor Schwann

    Theodor Schwann
    He confirmed that, "All living things are composed of cells and cell products".
  • Matthias Jakob Schleiden

    Matthias Jakob Schleiden
    Schleiden wrote Contributions to Phytogenesis in 1838, when he said that the different parts of the plant organism are composed of cells.
  • Cell Theory

    Cell Theory
    All living things are made up of cells, all cells come from pre-existing cells, cells are the main building blocks of cells, the well being of an organsim depends on the well-being of its cells.
  • Rudolf Virchow

    Rudolf Virchow
    He stated that "Every cells comes form a pre-existig cells."
  • The Electron Microscope

    The Electron Microscope
    An electron microscope is a type of microscope that uses a beam of electrons to light the specimen and produce a magnified image. Electron microscopes have a greater resolving power than a light-powered optical microscope, because electrons have wavelengths about 100,000 times shorter than visible light, and can achieve better than 50 pm resolution and magnifications of up to about 10,000,000x,
  • X-Ray Microscope

    X-Ray Microscope
    these microscopes use a beam of x-rays to create an image. Because of a small wavelength, the image quality is higher than in optical microscopes. The maximum useful magnification is therefore also higher and is between the optical microscopes and electron microscopes.
  • Scanning Tunneling Microscope

    Scanning Tunneling Microscope
    This type of Microscope can magnify up to 1 000 000 times! (STM) uses an electron beam not only to image things, getting resolution at the atomic level, but actually control them too.
