Who called Kern?
The core was also described in 1804 by Franz Bauer and in 1831 by the Scottish botanist Robert Brown in a lecture at the Linnean Society in London. Brown was studying orchids under a microscope when he noticed an opaque area, which he called the areola, or nucleus, in the cells of the flower’s outer layer.
How did the core get its name?
Interesting facts about the cell nucleus.
The nuclear envelope is destroyed during cell division, but is repaired after the separation of two cells. Some scientists believe that the nucleolus plays an important role in cell aging. The cell nucleus is named after the Scottish botanist Robert Brown.
Who was the first to see and name the nucleus?
Nobody imagined the modern atom, proposed by Niels Bohr in 1913, which is essentially a vacuum with all the positive charges concentrated in a tiny nucleus. In 1911, Rutherford, Marsden, and Geiger discovered the dense core by bombarding a thin layer of gold with alpha particles emitted by radium.
What’s in the core?
The nucleus is a membrane-bound organelle that contains the cells’ chromosomes. The pores in the nuclear membrane allow molecules to enter and leave the nucleus.
Who invented the electron?
Joseph John Thomson (J. J. Thomson, 1856-1940, see photo at the American Institute of Physics) is widely credited as the discoverer of the electron. Thomson was Cavendish Professor of Experimental Physics at Cambridge University from 1884 to 1919 and director of the Cavendish Laboratory.
Who discovered the electron?
In the 1880s and 1890s, scientists looked to cathode rays for a vector of the electrical properties of matter. His work led to the discovery of the electron by the English physicist J.J. Thompson
