Question

semipermeable cell membranes are made of phospholipids that form a bilayer. what major benefit does this arrangement of the membrane provide to the cell? both surfaces of the membrane can interact with water and other molecules. the cell is able to easily change size and shape. the cell has a greater level of structural support. both surfaces of the membrane are nonpermeable.

Explanation:

Phospholipid bilayers have hydrophilic heads and hydrophobic tails. The hydrophilic heads face outward, allowing both surfaces to interact with water - based environments and other polar molecules. This is crucial for cell - molecule interactions and maintaining cell function. The other options are incorrect as the bilayer isn't mainly for easy size/shape change, doesn't provide the main structural support (cell walls do in some cells), and the bilayer is semi - permeable not non - permeable on both surfaces.

Answer:

Both surfaces of the membrane can interact with water and other molecules.
