  • The Jesuit priest Athanasius Kircher showed, that maggots and other living creatures developed in decaying tissues.

    Those type of organisms are decomposers and feed on dead organisms.
  • Hooke published Micrographia, the first important work devoted to microscopical observation

    Hooke published Micrographia, the first important work devoted to microscopical observation

    He described the microscopic cells that made up the structure of a
    slice of cork and coined the term ‘‘cells’’ or ‘‘pores’’ to refer to these units
  • The particles that he saw under his microscope were motile and, assuming that motility equates to life, he went on to conclude, in a letter to the Royal Society, that these particles were indeed living organisms.

    When he put the particles under a microscope and that's when he realized that they were living organisms.
  • Hints at the idea that the cell is the basic component of living organisms emerged well before 1838–39, which was when the cell theory was officially formulated

    Cells are the building blocks to all living organisms.
  • The botanist Matthias Jakob Schleiden suggested that every structural elements of plants is composed of cells or their products.

    This when he discovered that plants are also made up of cells.
  • The most important breakthrough in neurocytology and neuroanatomy came in 1873 when Golgi developed the ‘black reaction'

    When the nervous system was also found to be made up of independent units, cell theory obtained its final triumph.
  • the Swiss embryologist Wilhelm His (1831–1904) put forward the idea that the nerve-cell body and its prolongations form an independent unit

    the Swiss embryologist Wilhelm His (1831–1904) put forward the idea that the nerve-cell body and its prolongations form an independent unit

    The nerve cell body form its own separate part.
  • Similar conclusions were reached, at the beginning of 1887, by another Swiss scientist, the psychiatrist August Forel (1848– 1931)

    Heim suggested that separation of cell units might be true of the central nervous system, August Forel had a similar idea.
  • Waldeyer introduced the term ‘‘neurons’’ to indicate independent nerve cells25,26. Thereafter, cell theory as applied to the nervous system became known as the ‘neuron theory

  • The term ‘‘ergastoplasm’’ (endoplasmic reticulum) was introduced in 1897

    The term ‘‘ergastoplasm’’ (endoplasmic reticulum) was introduced in 1897

    Towards the end of the nineteenth century, the principal organelles that are now considered to be parts of the cell were identified
