  2. Jan 23, 2009 · The term cell nucleus was used by Robert Brown for the first time in 1831 in a paper to the Linnean Society and it was published in 1833. At the time of publishing he did not realize that cell nucleus was present in cells other than those belonging to plants. During his stay in Australia Brown studied nearly 1700 plant species and other notable ...

  5. Mar 25, 2020 · Robert Brown contributed to cell theory by showing the radical motion of molecules within a cell under the light of a microscope. The Brownian method was named after Brown’s discovery of the way that the molecules moved. In 1802, Franz Bauer first discovered and described the nucleus of a cell.

  6. Brown focused much of his energy on the process of fertilization in plants, and chose the cells of Asclepiads and orchids to further his study. In them Brown noticed pollen traveling in and out of ovals in their cells. He termed this oval the "the nucleus". 1

  7. Brown also studied the anatomy of fossilized plants and plant reproduction. In 1831 while he was investigating plant fertilization, he noticed a small structure that occurred in all plant cells and that played an important part in cell division. He called it a nucleus, and that is the name by which it continues to be known.
