Detailed explanation-1: -In 1831, while investigating the fertilization mechanisms of plants in the Orchidaceae and Asclepiadaceae families, he noted the existence of a structure within the cells of orchids, as well as many other plants, that he termed the “nucleus” of the cell.

Detailed explanation-2: -The nucleus of the cell was discovered by Robert Brown. It was first described by Franz Bauer in 1804 and in more detail in 1831 by Scottish botanist Robert Brown in a talk at the Linnean Society of London.

Detailed explanation-3: -The nucleus was discovered by Robert Brown. He found an opaque area in plant cells and named it Nucleus.

Detailed explanation-4: -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.

Detailed explanation-5: -In a paper published in 1833, Brown became the first person to name and describe in detail the cell nucleus, though at the time he though it was a structure specific to the type of cells he was studying.
