Who discovered the nucleus of the cell?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Robert Brown.
The nucleus of the cell was discovered by Robert Brown in 1831.
Robert Brown, a Scottish botanist, is credited with the discovery of the cell nucleus in 1831 while studying plant cells under a microscope. Observing orchid epidermal cells, he noticed a distinct, rounded structure inside each cell and named it the nucleus. His work laid the foundation for later research into cell biology and the understanding of cellular structure and function. The nucleus is now known to be the control center of the cell, containing genetic material (DNA) and coordinating activities like growth, metabolism, and reproduction. Brown’s discovery remains a cornerstone in the field of cytology (cell biology).
Other Options:
-
Watson: James Watson is known for co-discovering the structure of DNA (double helix), not the cell nucleus.
-
Robert Hooke: Discovered cells in 1665 (in cork), but did not identify the nucleus.
-
Anton van Leeuwenhoek: First observed living cells and microorganisms, but not the nucleus.
