Correct answer: D. Robert Brown
- A. Robert Koch
- B. Robert Hooke
- C. Robert Mug Abe
- D. Robert Brown
Explanation
Robert Brown reported the nucleus in plant cells in 1831 after observing it as a distinct structure within the cell. Robert Hooke coined the term “cell” from cork observations, so students may choose Hooke if they confuse the discovery of cells with the discovery of the nucleus.
