Which discovery did not contribute to cell theory? all living things are made of cells. cells are the basic unit of function in living things. all cells come from other cells. all cells require atp for energy.

i am pretty sure the answer is A

All cells require ATP for energy

Explanation:

The first three statements are related to cell theory as they consider the cell as the structural and functional brick for living cells ("All living things are made of cells" and "Cells are the basic unit of function in living things") or describe a biological mechanism to explain the continuity of life ("All cells come from other cells"). The discovery of the fact that "All cells require ATP for energy" does not directly provide specific evidence for supporting the cell theory as this theory could be valid even if ATP wouldn't be the chemical energy source for the cell.

i think that is new experiments yield untrustworthy data and should be carefully considered, because you don't know what will happen with the experiments.
