Cell theory

History of Cell Theory Timeline

  • Micrographia was published

    Micrographia was published
    Hooke published Micrographia, the first important work devoted to microscopical observation. I picked this event because this was the start for investigating cells for Hooke.
  • "Nucleus"

    "Nucleus"
    The Scottish botanist Robert Brown was the first to recognize the nucleus (a term that he introduced) as an essential
    component of living cells. I picked this event because this is a important part of a cell.
  • "Plants are composed of cells"

    "Plants are composed of cells"
    The botanist Matthias Jakob Schleiden suggested that
    every structural element of plants is composed of cells or their products. I picked this event because this helped us understand how plants work and where they get their energy. It also aided in studying plant cells and how they are different from our cells.

    The Greatest Discovery in Scientific History

    This was when the Cell theory was discovered by Theodor Schwann. This is important because this discovery helped people understand life and how our bodies work. I picked this event because if this did not happen, we would not be able to make medicines and vaccines.
  • Cells form through Scission

    Cells form through Scission
    In the 1850s Robert Remak and Albert Kolliker who showed that cells are formed through scission of pre existing cells. This is important because this later became the basis of the theory of tissue formation. I selected this event because this greatly tied into the cell theory and formed the idea that cells come from other cells.
  • Cells come from cells

    Cells come from cells
    Virchow saw cells dividing and added that living cells arise only from other living cells. This is important because this breakthrough is a part of the cell theory. I selected this event because this leads directly to the cell theory and helped us achieve a understanding of life.
  • Period: to

    The Neuron Theory

    The Neuron Theory was created, establishing nerve cell characteristics. This is important because it helped understand how are brains function and how other parts of our bodies work. I selected this event because this also helped with making medicines and other essentials that we need.
  • Oil immersion lens

    Oil immersion lens
    The introduction of the oil immersion lens, the development of the microtome technique. This is important because this greatly improved microscopy and helped with formulating the Cell Theory. I selected this event because without these lenses, scientists might have not been able to further their investigation of cells.
  • The Black Reaction

    The Black Reaction
    Golgi developed the "black reaction." This is important because his investigations contributed to the foundations of the basic concepts of modern neuroscience. I selected this event because this was the most important breakthrough in neurocytology and this contributed to many things.
  • Independent Units

    Independent Units
    The Swiss embryologist Wilhelm His put
    forward the idea that the nerve-cell body
    and its prolongations form an independent
    unit. I picked this event because this sparked the idea of cells having different parts.
  • "Neurons"

    "Neurons"
    1891, Waldeyer introduced the term ‘‘neurons." This was important because neurons are a crucial part of our bodies. I selected this event because neurons are essential for every action that our body and brain carry out.
