Final answer:
Cells can differ in structure and function, and not all cells have the same structure.
Step-by-step explanation:
All cells have the same structure is NOT a true statement about differences between cells. While cells may have certain parts in common, such as the plasma membrane, cytoplasm, ribosomes, and DNA, cells can also have different organelles and structures. Cells with different functions often have different shapes as well. For example, a muscle cell is very different from a liver cell, which is very different from a skin cell.
