Cell Structure and Compartments
According to the fluid mosaic model of cell membranes,

the membrane is a highly mobile mixture of phospholipids and proteins
the most common type of molecules in the membrane are proteins
the unique properties of cell types are determined by their phospholipids
basic membrane structure results from how the proteins interact with water
