• A. Haeckel
• B. Virchow
• C. Hooke
• D. Schleiden

The statement that "cells arise from pre-existing cells" is attributed to Rudolf Virchow. This principle is a fundamental concept in cell theory, emphasizing that new cells are formed only from existing cells.

Key Figures in Cell Theory

• Rudolf Virchow: Proposed that all cells come from other cells.
• Matthias Schleiden: Contributed to the understanding that plants are made of cells.
• Theodor Schwann: Extended the cell theory to animals.
• Robert Hooke: First to observe and name cells, but did not formulate the idea of cell division.

Importance of Virchow's Contribution

Virchow's assertion was crucial in shaping our understanding of biology, reinforcing the idea that life is a continuous process of cellular reproduction.
