Which of the following is true? a) phospholipids can laterally diffuse along the plane of the membrane. b) phospholipids frequently flip-flop from one leaflet to the other. c) phospholipids occur in an uninterrupted sheet, with proteins restricted to the surfaces of the membrane. d) phospholipids are free to depart from the membrane and dissolve in the surrounding solution. e) phospholipids have hydrophilic tails in the interior of the membrane.

A). Phospholipids can laterally diffuse along the plane of the membrane.

Explanation:

The phospholipids are the class of lipids that forms the major part of all the cell membranes. They are capable of forming the lipid bilayer because of the amphiphilic characteristic. The structure of these phospholipids molecules consists of two of the hydrophobic tails and also consists of hydrophobic head that consists of a phosphate group.  

These phospholipids being in the lipid bilayer are capable of moving rotationally. These move laterally in one bilayer and they perform transverse movement in between the bilayers. The lateral movement is possible in membrane that exhibit a fluid structure.
