Nov 21, 2023 · Robert Brown contributed to the cell theory through his detailed description of the plant cell nuclei. He also coined the term ''nucleus,'' which scientists still use today.
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.
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...

Robert Brown FRSE FRS FLS MWS (21 December 1773 – 10 June 1858) was a Scottish botanist and paleobotanist who made important contributions to botany largely through his pioneering use of the microscope.
In 1831, Scottish botanist Robert Brown introduced the notion of the cell nucleus and in 1838, botanist Matthias Schleiden and zoologist Theodor Schwann enunciated the basic postulate of cell theory, according to which all living beings, plants and animals, are formed by cells, which they considered the fundamental vital unit of life.
The cell theory is one of the foundational tenets of biology and explains the relationship between cells and living things. Development of this theory occurred largely as a result of advancements in the field of microscopy. Cell Theory Timeline. Zacharias Janssen. Time: 1590 • Invented the first compound microscope.
