Schwann’s conclusions Original Cell Theory  1. the cell is the unit of structure, physiology, and organization in living things. 2. The cell retains a dual existence as a distinct entity and a building block in the construction of organisms. 3. Cells form by free-cell formation, similar to the form of crystals (spontaneous generation)]]> 2021-01-28 22:51:38 UTC https://padlet.com/tfarris21/je4gfbqx7k8ynmjz/wish/1138885334 tfarris21 https://padlet.com/tfarris21/je4gfbqx7k8ynmjz/wish/1138891899 In 1855 Rudolph Virchow, a German botanists- observed plant cells dividing, concluded that all cells come from pre-existing cells via cell division.

What theory did these scientists provide evidence for? The Cell Theory
2. What instrument was necessary before the cell theory could be developed? The microscope
3. Which 3 scientists directly contributed evidence for the cell theory? Matthias Schleiden, Theodore Schwann, and Rudolph Virchow
4. How did the earlier scientists and their contributions directly affect the discoveries of later scientists? For example what had to come first? The microscope had to be invented for these scientists to observe and record their findings. Without the microscope you cannot see these microscopic things.

Modern Tenets of the Cell Theory
1. All known living things are made up of cells
2. The cell is the structural and functional unit of all living things
3. All cells come from pre-existing cells by division mitosis /meiosis  (spontaneous generation does not occur)
4. Cells contains hereditary information which is passed from cell to cell during cell division
5. All cells are basically the same in chemical composition CHO (carbon, hydrogen, oxygen)
6. All energy flow (metabolism and biochemistry) of life occurs within cells
