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 unit of life, and all cells come from pre - existing cells. Let's analyze each option:

• Option 1: Some organisms (like bacteria) are single - celled. So, not all organisms are composed of multiple cells.
• Option 2: Different cells (e.g., nerve cells and red blood cells) have different structures and functions.
• Option 3: Non - living things (e.g., rocks) do not have cells.
• Option 4: This is in line with the principle of cell theory that all living cells come from other living cells.

Answer:

All living cells come from other living cells.
