Question

Which of the following is incorrect for Rudolf Virchow?

A. He gave the statement ‘Omnis cellula.
B. He modified the hypothesis of Schleiden and Schwann to give cell theory.
C. According to him, all cells arise from pre-existing cells.
D. He proposed to cell Theory but this theory did not explain how new cells are formed.

Answer 1

Hint: Virchow used the theory that all cells arise from pre-existing cells to lay the groundwork for cellular pathology, or the study of disease at the cellular stage. His work made it clearer that diseases occur at the cellular stage.

Complete Answer:
Virchow is known with many basic discoveries. His most well known scientific benefaction is the cell theory that is based on the work of Theodor Schwann. He was one of the first to recognize the work of Robert Remak, who displayed that the initiation of cells was the part of previously occurring cells.

Now, let us find the solution from the option.
- Rudolf Virchow has made many important discoveries. He is well recognized for his contribution to cell theory. He gave the statement that "Omnis cellula e cellula." According to him, all living cells are initiated from previous living cells.
- He first explained how new cells are formed from the existing cells. He modified the hypothesis of Schleiden and Schwann to give the cell theory a final shape.
- According to Schleiden and Schwann, the cells budded out from the nucleus.

Thus, the correct option is D. i.e. He proposed to cell Theory but this theory did not explain how new cells are formed.

Note: He developed the modern theory of pathological functions by his application of the cell theory to describe the result of disease in the tissues and organs of the body. He highlighted that diseases initiated, not in organs or tissues as usual, but mainly in their individual cells. Additionally, he worked powerfully for social recreations and gave to the development of anthropology as a modern science.
