Cell Theory Timeline

  • Robert Hooke published "Mitographia."

    Robert Hooke published "Mitographia."
    Robert Hooke coins the term cell. He used the term cells because when he looked at cells under a microscope, they reminded him of the rooms monks lived in. I chose this because it was a book devoted to microscopical observation.
  • Period: to

    Zoologist Theodore Schwann

    Schwann stated that "the elementary parts of all tissues are formed of cells." As well as that there was, "one universal principal of development for the elementary parts of organisms...and this principle is is in the formation of cells." I decided to use this because one of the main ideas of cell theory is that cells are the building blocks of life.
  • Robert Remak refutes the previous free cell theory.

    Robert Remak refutes the previous free cell theory.
    This is important because without this we would think that cells spontaneously emerge and reproduce instead of being created from preexisting cells.
  • Robert Brown seeing cells in plants.

    Robert Brown seeing cells in plants.
    This is important because it helped people realize that all living things have cells not just humans or animals. I picked this because it is one of the most valuable discoveries moving forward in cell discovery.
  • The nucleus is identified as an essential constituent of living cells.

    The nucleus is identified as an essential constituent of living cells.
    The Scottish botanist Robert brown introduced the term and function of the nucleus. This is important because the nucleus is the most vital part of the cell.
  • Period: to

    Carl Deiters' posthumous book.

    A book by Carl Deiters, that was published posthumously, showed descriptions and drawings of nerve cells studied by using histological methods and microdissections made with thin needle under the microscope.
  • Rudolf Virchow and Albert Killiker showed that cells are formed through scissions of preexisting cells.

    Rudolf Virchow and Albert Killiker showed that cells are formed through scissions of preexisting cells.
    I chose this event because it is important to the cell theory we now know to be true, without this we would not understand how cells actually formed.
  • Walther Flemming introduced the term "mitosis."

    Walther Flemming introduced the term "mitosis."
    This is important because Flemming provided a detailed description of the functions of mitosis, a vital part of the cell cycle.
  • Waldeyer introduced the term "neurons."

    Waldeyer introduced the term "neurons."
    He used the term neurons to indicate independent nerve cells. Therefore, cell theory applying to the nervous system became known as "neuron theory." This is important because the nervous system is vital to our body's function, so without this we wouldn't be able to do proper research on the functions of it. As well as the things that affect the nervous system.
  • The mitochondria was discovered.

    The mitochondria was discovered.
    I chose this because without the mitochondria, the cell would not have enough energy to function. The discovery of it is important to better understand how cells work.
