he saw particles under his microscope were motile and, assuming that motility equates to life, he went on to conclude that these particles were indeed living organisms.
-
The micrographia is the first important work
devoted to microscopical observation, and
showed what the microscope could mean
for naturalists. I choose this because it was the first important work -
he was the first to recognize the nucleus as an essential constituent of living cells in 1831.Brown recognized the general occurrence of the nucleus in these cells and apparently thought of the organization of the plant in terms of cellular constituents. He also introduced the name nucleus.
-
the Achromatic microscopes allow more precise histological observation. I chose this because Achromatic microscopes were technical improvements -
Wilhelm put forward the idea that the nerve-cell body and its prolongations form an independent. He suggested that a separation of cell units might be true of the central nervous system. The nervous
system began to be considered, like any other tissue, as a sum of anatomically and functionally independent cells, which interact by contiguity rather than by continuity. -
Some cellular components, such as the nucleus, had been visualized, and the occurrence of these structures in cells of different tissues and organisms hinted at the possibility that cells of similar organization might underlie all living matter. I chose this because cells are the building block of all living things
-
Robert Remak, Rudolf Virchow and Albert Kölliker who refuted the free cell formation also showed that cells are formed through scission of pre-existing cell. They created a part of the cell theory that cells are formed from pre-existing cells. -
the the development of the microtome technique and the use of new fixing methods and dyes greatly improved microscope. The microscope allows people to see cells up close -
The most important breakthrough in neurocytology and neuroanatomyis when Gologi develops black reaction. I chose this because it is the most important breakthrough -
Waldeyer introduced the term ‘‘neurons’’ to indicate independent nerve cells. There after, cell theory as applied to the nervous system became known as the ‘neuron theory. I chose this because he basically started neuron theory.
