Theodor Schwann
Theodor Schwann (German pronunciation: [ˈteːodoːɐ̯ ˈʃvan]; 7 December 1810 – 11 January 1882) was a German physician and physiologist. His most significant contribution to biology is considered to be the extension of cell theory to animals.

What are the 3 parts to the cell theory?

The three parts of the cell theory are:
  • All living things are composed of cells.
  • Cells are the basic units of structure and function for living things.
  • All cells come from pre-existing cells. Also, organisms grow by “adding on more cells” NOT by increasing the size of their cells.
