Who among the following was the first to describe the nucleus as a cell organelle?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. Robert Brown.
Robert Brown, a Scottish botanist, was the first to describe the nucleus in 1831 while studying plant cells under a microscope. He observed a distinct, dense structure inside the cell, which he named the nucleus. Brown’s discovery was crucial because it identified a central component of the cell, later understood to control many cellular activities. This finding laid the foundation for cell biology, helping scientists realize that the nucleus plays a vital role in heredity and cell function. Brown’s work remains fundamental in understanding cell structure and organization.
