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? o both surfaces of the membrane can interact with water and other molecules. o the cell is able to easily change size and shape. o the cell has a greater level of structural support. o both surfaces of the membrane are nonpermeable.

Explanation:

Phospholipids in a bilayer have hydrophilic heads and hydrophobic tails. The hydrophilic heads face outward, allowing both surfaces of the membrane to interact with water - based environments and other molecules, which is crucial for cell - environment interactions and transport. The other options are incorrect as the bilayer doesn't mainly contribute to easy size/shape change, greater structural support compared to other cell structures like the cell wall in plants, and the membrane is semi - permeable not non - permeable.

Answer:

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