Who is Robert Brown and what did he discover?
Robert Brown was a Scottish Botanist who was responsible for discovery of the nucleus of the cell and he is responsible for discovering the Brownian motion which is the random movement of microscopic particles.
What do we called the first organelle discovered and named by Robert Brown in 1833?
the cell nucleus
In a paper read to the Linnean society in 1831 and published in 1833, Brown named the cell nucleus.
What was Robert Brown contribution to cell theory?
Brown published his research findings and gave speeches. His discovery of the nucleus and its role helped to put together the cell theory, which states that all living organisms are composed of cells, and cells come from pre-existing cells. Brown’s discovery helped to confirm the second half of the cell theory.
What was the significant discovery of Robert Brown?
Robert Brown (1773-1858) discovered the nucleus of a cell. In 1831, Scottish botanist Robert Brown (1773–1858) was the first to describe observations of nuclei, which he observed in plant cells.

What are the contribution of Robert Brown?
Robert Brown, (born December 21, 1773, Montrose, Angus, Scotland—died June 10, 1858, London, England), Scottish botanist best known for his descriptions of cell nuclei and of the continuous motion of minute particles in solution, which came to be called Brownian motion.
How did Robert Brown change the world?
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.” He also developed alternative plant classification …
What did Robert Brown experiment with?
In 1827, the Scottish botanist Robert Brown looked through a microscope at pollen grains suspended in water, and discovered what we now call Brownian Motion. It was an unintentional discovery. He was not looking for the effect that now bears his name, but was, rather, curious about reproduction.
How did Robert Brown explain what he saw?
Answer: Robert Brown explained what he saw by stating that the pollen grains were alive and living things. Explanation: Because the pollen grains were moving in random directions.
Who gave jobs to Robert Brown?
He studied medicine at the Universities of Aberdeen and Edinburgh and spent five years in the British army serving in Ireland as an ensign and assistant surgeon (1795–1800). A visit to London in 1798 brought Brown to the notice of Sir Joseph Banks, president of the Royal Society.
What is a fun fact about Robert Brown?
Robert Brown was a Scottish botanist who pioneered the use of the microscope in botany, which he used to describe the nucleus of a cell. He also developed the idea of what is now called the Brownian motion which explained the random movement of minute particles in a fluid.
