Question

All cells arise from the pre-existing cells. This theory is proposed by____________.

• A. Rudolf Virchow
• B. Leeuwenhoek
• C. Robert Hooke
• D. Darwin

Answer 1

The correct option is A Rudolf Virchow

Rudolf Virchow expanded the cell theory and suggested that all cells arise from the pre-existing cells (Omnis cellula-e-cellula). Leeuwenhoek discovered free-living cells in pond water with the help of an improved version of microscope. Robert Hooke saw the honeycomb like structure in the slice of cork and he called these boxes or compartments as cells. Darwinian theories are related to evolution.
