History of the Cell :: essays research papers

History of the cubicle          The word galvanic cell was coined by Englishman Robert Hooke (1635-1703), after viewing slices of cork in a microscope. The word cell was derived from the Latin word cella meaning teeny container.     The microscope created mod possibilities in the study biology. It whollyowed scientists to look into a completely new view of cellular biology. Galileo is credited with the invention of the microscope. Two of the main pioneers in microscope usage were Robert Hooke and Antonie von Leeuwenhoek.     Rene Dutrochet discovered, in 1824, that the cell is the fundamental element in the expression of life. The first sightings of the actual movement of a cell were made by Robert Brown in 1827. Brown also discovered the nucleus in 1833. In Berlin, Johannes Muller made the connection between biology and medicine, others soon followed Muller and his connective thinking. One to fol low Muller was Theodore Schwann. Schwann created the idea of the "cell theory" in the 1830s and stated that plants consisted of cells. His statement was made after Matthias Schleiden (1804 - 1881) had persistent in 1838 that animals are composed of cells. In 1939 Schwann also stated that all organisms consist of one or more cells, and that the cell is the basic body structure for all of life.     German Pathologist by the name of Rudolf Virchow (1821 - 1902) altered the sentiment of cellular biology with his statement that "every cell comes from a cell. non even twenty years after this statement, processes of cell reproduction were being described.      In 1898, Camillo Golgi developed a staining technique using facile nitrate that allows the identification of the cellular organelle that now bears his name, the Golgi apparatus. The Golgi apparatus is answerable for processing the proteins that are synthesized in the endoplasm ic reticulum.     In 1953 Stanley Lloyd Miller conducted his famous autochthonic soup experiment. His experiment may have possibly shown how lifes building blocks here on earth may have formed. In the experiment he subjected a gaseous mixture of hydrogen, water, methane, and ammonia to an electric discharge for one week. Instead of him showing everyone that spontaneous generation was possible, his primaeval soup showed him that it was not. Miller made sure that there was no type O in his design, but all throughout life there has been type O present.
