Which of the following statements about a typical plasma membrane is correct? The hydrophilic interior of the membrane is composed primarily of the fatty acid tails of the phospholipids. Carbohydrates on the membrane surface are important in determing the overall bilayer structure. Phospholipids are the primary component that determines which solute can cross the plasma membrane. The two sides of the plasma membrane have different lipid and protein composition. The plasma membrane is covalently linked network of phospholipids and proteins that controls the movement of solutes into and out of a cell.

Osmosis

In simple words, osmosis is the slow, gradual movement of a liquid through a membrane. But there are nuances to this process. For instance, there has to be an imbalance in the distribution of solute in the liquid on either side of the membrane, which has to be semipermeable. The liquid in the region with a lower solute concentration moves to the region with a higher concentration, thereby displacing the solution in the process. The objective is to equalize the concentration of molecules on both sides of the membrane; the displacement of liquid can be viewed as a byproduct of this equalization. Since there is no energy required to carry osmosis, it is considered a passive process.
