How did Louis Pasteur contribute to the development of cell theory?
A
He provided experimental evidence against spontaneous generation, supporting the idea that cells come from pre-existing cells.
B
He discovered the nucleus and showed it was essential for cell division.
C
He first observed cells using a compound microscope and coined the term "cell."
D
He proposed that all living organisms are composed of one or more cells and that the cell is the basic unit of life.
Verified step by step guidance1
Understand the historical context of cell theory, which includes key contributions from various scientists over time.
Recognize that Louis Pasteur's main contribution was through his experiments that disproved spontaneous generation, the idea that life could arise from non-living matter.
Know that by disproving spontaneous generation, Pasteur supported the concept that cells arise only from pre-existing cells, reinforcing a fundamental principle of cell theory.
Distinguish Pasteur's work from other contributions: for example, Robert Hooke first observed cells, and Schleiden and Schwann proposed that all living organisms are made of cells.
Conclude that Pasteur's experimental evidence strengthened the cell theory by confirming that cells do not spontaneously appear but come from existing cells.
