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:

• Option 1: Some organisms (like bacteria) are unicellular, so "multiple cells" is wrong.
• Option 2: Cells have different structures/functions (e.g., muscle vs. nerve cells), so this is incorrect.
• Option 3: Non - living things (like rocks) don't have cells, so this is wrong.
• Option 4: Cell theory states that all living cells arise from pre - existing living cells, which is correct.

Answer:

D. All living cells come from other living cells. (Note: Assuming the options are labeled A - D as per the order: A. All organisms are composed of multiple cells. B. All cells have the same structure and function. C. Cells are found in everything on Earth. D. All living cells come from other living cells.)
