Correct Answer: Option D - Rudolf Ludwig Carl Virchow proposed his famous formula ''Omnis cellula-e-cellula" in the year 1855. It means ''every cell stems from another cell'' . This formula is significant in cell theory because it established the concept that new cells are formed by the division of existing cells. This principle contradicted the earlier notion of spontaneous generation and emphasized that cellular reproduction is a cycle where cells give rise to new cells .
