Rudolf Virchow observed that all cells arise from pre-existing cells, encapsulated in his famous phrase "Omnis cellula e cellula." This contradicted the prevailing notion of spontaneous generation and laid the foundation for the cell theory. His work emphasized the importance of cell division in the growth and development of tissues and organisms, highlighting the continuity of life through cellular replication. Virchow's insights were pivotal in advancing our understanding of pathology and the role of cells in disease.
It was Ruldof Virchow who thought of that theory. The process is called MITOSIS and MEIOSIS. Most of the time when people refer to "cell division," they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells. For Mitosis : Parent Cell, DNA replicates and 2 daughter cells. For Meiosis : Parent Cell, DNA replicates, 2 daughter cells and 4 daughter cells.
By 1855 he already had the idea that 'cells originate from pre-existing cells'.

Rudolf Virchow------------------------------No, Virchow plagiarised the work of Robert Remak who first showed that the origins of cells was the division of pre-existing cells.

In 1859, the German pathologist R. Virchow made a significant change in the cell theory concerning the formation of new cells. Contrary to the views of Schleiden and Schwann, R. Virchow argued that cells arise only by reproduction (division)
Rudolf Virchow did not directly help Robert Hooke, as they lived in different time periods—Hooke in the 17th century and Virchow in the 19th century. However, Virchow built upon Hooke's foundational work in cell theory. Hooke was the first to use the term "cell" in his observations of cork, while Virchow later asserted that all cells arise from pre-existing cells, advancing our understanding of cellular biology. Their contributions collectively shaped the field of histology and cell theory.
The major scientists who made contributions to the discovery of cells are Robert Hooke, Theodor Schwann, Matthias Schleiden, Rudolf Virchow, and Antonie van Leeuwenhoek. Hooke coined the term "cell," Schwann and Schleiden proposed the cell theory, Virchow added the concept of cells arising from pre-existing cells, and Leeuwenhoek used microscopes to observe cells for the first time.
Rudolf Virchow added the principle of cell division to the cell theory. He stated that cells arise only from pre-existing cells, contradicting the idea of spontaneous generation. This concept further solidified the understanding that cells are the fundamental units of life.
