Which is the MOST accurate statement comparing cell membranes and cell walls?

Question

• A. Cell walls prevent everything from entering the cell, while cell membranes allow some things to enter.
• B. Cell membranes function mostly as selectively permeable gatekeepers, while cell walls function mainly as support systems.
• C. Cell membranes are found only in animal cells; cell walls are found only in plant cells.
• D. Cell walis function mostly for photosynthesis, while cell membranes function mostly for cellular respiration.

Answer 1

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.

This statement correctly highlights the primary functions of cell membranes and cell walls. Cell membranes are selectively permeable, allowing certain substances to enter and exit the cell, while cell walls provide structural support and protection to the cell.
