1 Jan 1838 Jahr - M.J. Schleiden (1804-1881) and T.S. Schwann (1810-1882)

Beschreibung:

Schleiden and Schwann worked together. Schleiden studied plant cells and observed nuclei. He concluded that each cell develops from the nucleus. Schwann studied animal cells and found similarities between animal an plant cells. He discovered that all organisms contained cells. Also, he developed the first principle of the cell theory-- "all cells are composed of one or more cells". The team both still believed in abiogenesis.
