The MOST accurate statement comparing cell membranes and cell walls is:
B. Cell membranes function mostly as selectively permeable gatekeepers, while cell walls function mainly as support systems.
Cell membranes are indeed selectively permeable, allowing certain substances to pass while blocking others, while cell walls primarily provide structural support and protection to the cell.
