Who first postulated that cells are generated from pre-existing cells?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. Rudolf Virchow.
Rudolf Virchow, a German physician and pathologist, first postulated in 1855 that all cells arise from pre-existing cells, coining the famous phrase 'Omnis cellula e cellula.' This idea opposed earlier theories of spontaneous generation and built upon the cell theory developed by Schleiden and Schwann. Virchow's insight was crucial in advancing the understanding of cellular biology, laying the foundation for modern pathology. His concept emphasized that diseases originate at the cellular level, shifting medical focus toward cellular processes. Virchow's work helped establish cell division as the fundamental mechanism of biological continuity and growth, revolutionizing biological and medical sciences.
