Each membrane is a phospholipid bilayer with proteins embedded in it.

This description applies to all membranes, the internal ones as well as the plasma membrane (the one surrounding the cytoplasm).

What type of lipid molecules do membranes consist of?

Phopholipids - They have a hydrophillic head that is positioned to the inside of the cell and the outside environment. They also have hydrophobic tails that point towards each other inside the membrane. This is why cell membranes are referred to as lipid bilayers. They are 2 layers of phospholipids organzied by their interaction with water.
