Question

The concept of "Omnis cellula-e cellula " regarding cell division was first proposed by:

• A. Rudolf Virchow
• B. Theodore Schwann
• C. Schleiden
• D. Aristotle

Answer 1

The Correct Option is A

To solve the question about the origin of the concept "Omnis cellula e cellula", we first need to understand what this phrase means. The Latin term "Omnis cellula e cellula" translates to "every cell from a cell," which is a fundamental concept in cell theory regarding the division and origin of cells.

This concept was first proposed by Rudolf Virchow, a prominent German physician, pathologist, and anthropologist in the 19th century. Virchow is regarded as one of the founders of modern pathology and is known for his advancements in public health.

Here's a detailed look at why Rudolf Virchow is the correct answer:

• Rudolf Virchow: Proposed the statement "Omnis cellula e cellula" in 1855, emphasizing that new cells are formed only by the division of existing cells. This statement is a key part of cell theory, rejecting the idea of spontaneous generation.
• Theodore Schwann: Alongside Matthias Schleiden, Theodore Schwann developed the cell theory in the 1830s, but he did not specifically propose the concept of cell division as elucidated by Virchow.
• Schleiden: Worked with Schwann on the formulation of the original cell theory but did not elaborate on the concept of cells emerging from pre-existing cells.
• Aristotle: An ancient Greek philosopher who contributed to many fields but did not propose the concept of cell division as cells were unknown in his time.

Thus, the correct answer is Rudolf Virchow, as he clearly articulated the idea that cells arise from existing cells, a pivotal concept in the understanding of biology and cellular processes.
