Correct Answer
(A) Rudolf Virchow
Solution & Explanation
Answer: (A) Rudolf Virchow Solution: Rudolf Virchow (1855) first explained that cells divide and new cells arise from pre-existing cells, expressed as 'Omnis cellula-e cellula'. Schleiden and Schwann formulated the original cell theory but could not explain how new cells form. Hence Virchow is the correct proposer of this concept. NCERT Reference: Ch 8, p.88, lines 11-13: "Rudolf Virchow (1855) first explained that cells divided and new cells are formed from pre-existing cells (Omnis cellula-e cellula)."
