Spontaneous generation.
The idea that all living cells come from preexisting living cells was proposed by Rudolf Virchow in 1855. This principle is known as biogenesis.

Louis Pasteur provided experimental proof for Virchow's biogenesis theory by conducting experiments that showed that living organisms only arise from pre-existing living organisms, refuting the theory of spontaneous generation. His swan-neck flask experiment demonstrated that microorganisms in the air did not spontaneously generate in sterile broth, supporting the idea that living organisms come from other living organisms.
The cell theory was developed by three scientists: Matthias Schleiden, Theodor Schwann, and Rudolf Virchow. Schleiden and Schwann proposed that all living things are composed of cells, while Virchow added that cells arise from pre-existing cells.
The cell theory is credited to Matthias Schleiden, Theodor Schwann, and Rudolf Virchow. Schleiden and Schwann proposed that all living organisms are composed of cells, while Virchow added that cells only arise from pre-existing cells.
Theodor Schwann was the scientist who determined that all animals were made out of cells.

Louis Pasteur provided experimental proof for Virchow's biogenesis theory by conducting experiments that showed that living organisms only arise from pre-existing living organisms, refuting the theory of spontaneous generation. His swan-neck flask experiment demonstrated that microorganisms in the air did not spontaneously generate in sterile broth, supporting the idea that living organisms come from other living organisms.
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.
The cell theory was developed by three scientists: Matthias Schleiden, Theodor Schwann, and Rudolf Virchow. Schleiden and Schwann proposed that all living things are composed of cells, while Virchow added that cells arise from pre-existing cells.
Rudolf Virchow contributed to the understanding of the concept of spontaneous generation by asserting that "omnis cellula e cellula," meaning "all cells come from cells." This challenged the idea of spontaneous generation, which posited that living organisms could arise from non-living matter. Virchow's work emphasized that life originates from pre-existing living cells, supporting the germ theory of disease and laying the groundwork for modern cellular biology. His findings reinforced the idea that life cannot spontaneously emerge from inanimate substances.

The three scientists credited with developing the Cell Theory are Matthias Schleiden, Theodor Schwann, and Rudolf Virchow. Schleiden and Schwann proposed that all living organisms are composed of cells, while Virchow later suggested that cells arise from pre-existing cells through division.
