Which of the following is the most accurate statement comparing cell membranes and cell walls?

a
Cell walls function mostly for photosynthesis while cell membranes function mostly for cellular respiration.
b
Cell membranes are found only in animal cells; cell walls are found only in plant cells.
c
Cell walls prevent everything from entering the cell, while cell membranes allow some things to enter.
d
Cell membranes function mostly as selectively permeable gatekeepers while cell walls function mainly as support systems.

The most accurate statement comparing cell membranes and cell walls is:

d. Cell membranes function mostly as selectively permeable gatekeepers while cell walls function mainly as support systems.

This statement accurately reflects the roles of both structures. Cell membranes control the entry and exit of substances in and out of the cell, while cell walls provide structure and support, particularly in plant cells.
