Question
________ gave the final form to the cell theory.
- Leeuwenhoek
- Rudolph Virchow
- Robert Hooke
- Schwann
Hint:
The cell theory that was first given by Schleiden and Schwann failed to suggest how cells are formed
The correct answer is: Rudolph Virchow
The cell theory first given by Schleiden and Schwann failed to suggest how cells are formed. Therefore, later in the year 1855, a scientist named Rudolf Virchow modified this cell theory and stated that new cells are formed from the pre-existing cells i.e. Omnis cellula-e cellula. Thereby, he modified the cell theory and gave a final shape to the cell theory. This was the final modification of the cell theory.
