Describe the structure of the plasma membrane according to fluid mosaic model

According to fluid mosaic model the plasma membrane consist:

– A bimolecular phospholipid layer with inwardly directed hydrophobic tails and outwardly directed hydrophilic heads. This phospholipid layer is capable of much molecular movement, i.e. is fluid in nature

– A variety of globular proteins molecules with an irregular arrangement within the bimolecular phospholipid layer. Some proteins occur on the surface of phospholipid layer (peripheral or extrinsic proteins) while others extend into it (transmembrane protein). Viewed from the surface, the proteins are dotted throughout the phospholipid layer in mosaic arrangement. Hence the name fluid mosaic model.
