When did Robert Brown discovered the nucleus of the cell?
Robert Hooke discovered the existence of cells in 1665 using a microscope.
Robert Brown in 1831. Hope this helps! -Zoey Brown
He discovered the cell nucleus within cells as one of his major accomplishments
It Was Robert brown,a scottish botanist.
he observe the theory cells on microscope!
Robert Hooke Discovered the cell in 1665
He found them inside a piece of dead cork with a microscope. He was looking at this piece of cork because King Charles II asked him to.
By 1855 he already had the idea that 'cells originate from pre-existing cells'.
yes he did
he didn't he discovered the nucleolus
Cell nucleus discovery The question is debatable as Thonius Philips van Leeuwenhoek (October 24, 1632 - August 30, 1723)1, Dutch scientist first observed t…he cell nuleus. "In 1682 he clearly described the nucleus within the red blood cells of fish, and in 1683 he noticed the sedimentation of erythrocytes from a suspension and their lysis upon addition of water."2 It was Robert Brown (December 21, 1773-June 10, 1858)3 a Scottish Botanist who observed and gave the name "cell nucleus". Brown, is best known for the discovery of Brownian motion random movement within fluids due to molecular energy of fluid and also used as a mathematical model for Stochastic processes (random i.e. financial markets, atmospheric events).2,4 Some sources site Brown and not van Leeuwenhoek as the discoverer.5 http://en.wikipedia.org/wiki/Anton_van_Leeuwenhoek1 http://www.bookrags.com/Anton_van_Leeuwenhoek2 http://en.wikipedia.org/wiki/Robert_Brown_(botanist)3 http://www.brianjford.com/wbbrowna.htm4 http://science.discovery.com/convergence/100discoveries/big100/biology.html5
Robert Brown 1773-1858, Scottish botanist and botanical explorer. In 1801 he went as a naturalist on one of Matthew Flinders's expeditions to Australia, returning (1805) to En…gland with valuable collections. In his Prodromus florae Novae Hollandiae et Insulae Van Diemen (1810) he described Australian flora. A leading botanist of his day, he served as librarian to the Linnaean Society and to Sir Joseph Banks and later as curator at the British Museum. He observed http://wiki.answers.com/doc/1E1-Brownian.html in 1827, discovered the cell nucleus in 1831, and was the first to recognize gymnosperm as a distinct angiosperm. His studies of several plant families and of pollen were also notable.
