Question

Who gives the idea of cell arising from pre-existing cells?

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

Hint:

Virchow's work in pathology laid the groundwork for understanding the origins of cells, which is a cornerstone of cellular biology today.

Answer 1

The Correct Option is D

Step 1: Introduction to the Concept

One of the most essential ideas in modern biology is the principle that new cells can only arise from existing cells. This concept changed how scientists understand reproduction, tissue repair, and biological development.

Step 2: Origin of the Idea

The idea that all cells come from pre-existing cells was first proposed by Rudolf Virchow, a German physician, pathologist, and biologist.

Step 3: The Latin Phrase – Omnis Cellula e Cellula

Virchow expressed his idea with the Latin phrase “Omnis cellula e cellula,” which means "every cell from a cell." This refuted the old notion of spontaneous generation.

Step 4: Contribution to Modern Cell Theory

This concept became a fundamental part of modern cell theory, which consists of three key principles:

• All living organisms are made up of one or more cells.
• The cell is the basic unit of structure and function in living organisms.
• All cells arise from pre-existing cells.

Step 5: Biological Significance

The idea highlights the continuous and cyclical nature of life at the cellular level. From plant growth to human healing, all biological processes begin with a parent cell.

Step 6: Impact on Science

Virchow’s theory laid the foundation for major scientific advancements in cell biology, cancer research, regenerative medicine, and microbiology. It helped biology evolve into an evidence-based discipline.

Final Summary

Rudolf Virchow is credited with the statement “Omnis cellula e cellula”, meaning “every cell arises from a pre-existing cell.” This idea became a cornerstone of cell theory and transformed our understanding of how life continues and regenerates.
