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:

Cell theory states that all living things are made of cells, cells are the basic units of life, and all cells come from pre - existing cells.

• “All organisms are composed of multiple cells” is incorrect because there are single - celled organisms (e.g., bacteria).
• “All cells have the same structure and function” is wrong as different cells (e.g., nerve cells and red blood cells) have different structures and functions.
• “Cells are found in everything on Earth” is false; non - living things (e.g., rocks) do not have cells.
• “All living cells come from other living cells” aligns with the cell theory.

Answer:

All living cells come from other living cells.
