- In 1833, Robert Brown discovered the nucleus of the cell (basically, the house in our analogy). Hence, some cells had walls, others didn’t, but they all had jelly and they had a nucleus. This nucleus became very important to figure out how cells lived and died.

In a paper read to the Linnean society in 1831 and published in 1833, Brown named the cell nucleus. The nucleus had been observed before, perhaps as early as 1682 by the Dutch microscopist Leeuwenhoek , and Franz Bauer had noted and drawn it as a regular feature of plant cells in 1802, but it was Brown who gave it the name it bears to this day ...

He recognised and described the existence of the cell nucleus and stomata (breathing pores that act as gateways, in order to exchange gases with the atmosphere). The Linnean Society are the caretakers of Brown’s microscope, as restored by Prof Brian J Ford, on which his theory of Brownian motion was discovered.
Robert Brown, a botanist, collected, studied and classified thousands of plant flora he collected from the Flinders expedition to Australia in 1801 - 1805. He described Brownian motion, the movement of small particles in solution, which is named after him and he described and named the plant cell nuclei.

The Scottish botanist Robert Brown (1773– 1858) was the first to recognize the nucleus (a term that he introduced) as an essential constituent of living cells (1831). In the leaves of orchids...
