Which of the following is a premise or tenet of cell theory? Al cells arise from othercells All living cells require water for survival All living things are only composed of cells

The correct answer is **All cells arise from other cells**. This is one of the fundamental tenets of cell theory.<br /><br />While the other two statements are generally true (all living cells *do* require water, and all living things *are* composed of cells), they are not considered core principles of *cell theory* itself. Cell theory specifically focuses on the origin and nature of cells.<br />
