What is the significance of Rudolf Virchow's conclusion in Cell Theory?

Back

Rudolf Virchow concluded that all cells arise from other cells, which emphasizes the continuity of life and the process of cell division.

Front

How does Cell Theory explain the process of cell division?

Back

Cell Theory explains that when cells are damaged, new cells are created through the process of cell division, as cells come from previously existing cells.

What role did Robert Hooke play in the development of Cell Theory?

Back

Robert Hooke is credited with coining the term 'cell' after observing cork under a microscope.
