Question

according to the cell theory, which describes cells? all organisms are composed of multiple cells. all cells have the same structure and function. cells are found in everything on earth. all living cells come from other living cells.

Explanation:

1. Analyze the first option: The cell theory states that some organisms (like bacteria) are unicellular, so "all organisms are composed of multiple cells" is incorrect.
2. Analyze the second option: Cells have different structures and functions (e.g., muscle cells vs. nerve cells), so this is wrong.
3. Analyze the third option: Non - living things (like rocks) do not have cells, so this is incorrect.
4. Analyze the fourth option: One of the tenets of the cell theory is that all living cells come from pre - existing (other living) cells.

Answer:

D. All living cells come from other living cells. (Note: Assuming the options are labeled A, B, C, D in order. If the original options have different labels, adjust accordingly. The correct statement is "All living cells come from other living cells".)
