Question

the scientist (scientists) given credit for adding the third tenet (all cells come from preexisting cells) to the cell theory is (are) robert hooke. mathias schleiden and theodore schwann. rudolf virchow. carl woese. j. craig venter. clear selection

Explanation:

Robert Hooke coined the term "cell" but did not contribute to the third tenet. Schleiden and Schwann developed the first two tenets of cell theory (all organisms are made of cells, cells are the basic unit of life). Rudolf Virchow proposed the third tenet that all cells arise from preexisting cells. Carl Woese focused on archaea, and J. Craig Venter worked on genome sequencing, neither related to this cell theory tenet.

Answer:

C. Rudolf Virchow.
