Biology benchmark 2 semester exam fall 24

Question

Which is the MOST accurate statement comparing cell membranes and cell walls
A cell wall prevents everything from entering the cell, while cell membranes allow some things to enter
A cell membrane fuction mostly as selectively permeable gatekeepers, while cell walls fuction mainly as support systems
Cell membranes are found only in animal cells,cell walls are found only in plant cells
Cell Walls function mostly for photosynthesis while sale membranes function mostly for cellular respiration

Answer 1

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

A cell membrane functions mostly as selectively permeable gatekeepers, while cell walls function mainly as support systems.

This statement correctly identifies the primary functions of cell membranes and cell walls. Cell membranes regulate the movement of substances in and out of the cell, while cell walls primarily provide structural support and protection for the cell.
