Answers
Answer:
Although Scottish botanist Robert Brown (1773-1858) was responsible for discovering the nucleus of a cell, he is perhaps best known for his discovery of the random movement of microscopic particles in a surrounding solution, later referred to as "Brownian motion."
Answer:
Robert Brown FRSE FRS FLS MWS (21 December 1773 – 10 June 1858) was a Scottish botanist and palaeobotanist who made important contributions to botany largely through his pioneering use of the microscope. His contributions include one of the earliest detailed descriptions of the cell nucleus and cytoplasmic streaming; the observation of Brownian motion; early work on plant pollination and fertilisation, including being the first to recognise the fundamental difference between gymnosperms andangiosperms; and some of the earliest studies in palynology. He also made numerous contributions to plant taxonomy, including the erection of a number of plant families that are still accepted today; and numerous Australianplant genera and species, the fruit of his exploration of that continent with Matthew Flinders.
