M. J. Schleiden:
In the year 1838, a German botanist presented the first cell theory (Although his theory was ultimately disproved, it did contribute to a change in scientific focus to cellular processes.)
What is cell?All living creatures and body tissues are made up of the smallest unit that can live on its own. The cell membrane, nucleus, and cytoplasm are the three primary components of a cell. The cell membrane encloses the cell and regulates the molecules that enter and exit it.
His theory: Cells make up all plant tissues, and an embryonic plant is made up of just one cell. He declared that the cell is the fundamental building block of all plant matter.
Louis Pasteur- 1855 - German physiologist, physician, pathologist; and anthropologist. Added a third to the cell theory: Omnis Cellula e cellula (all cells develop only from existing cells).- Implied that there was no Spontaneous generation.
Rudolf Virchow- In 1862 he conducted a famous experiment supporting the theory that cells can only come from other cells.
His experiment:
Steralized flasks with straight and curved necks were used to heat nutrient broths. Bacteria only developed in the straight necks because bacteria cells from the air settled in the S-shaped necks' curves. Spontaneous gen did not produce proven cells in the broth.
