What is the plasma membrane aka phospholipid bilayer?
Name the three main components of a eukaryotic cell?
The plasma membrane of a cell consists of?
The plasma membrane of a cell consists of the phospholipid bilayer and proteins embeded in lipid bilayer in a mosaic manner . The phospholipid bilayer is formed by phospholipids that have a polar head , and a non-polar tail of fatty acids . Embedded in it, we can find proteins with a variety of functions including the transport of molecules across the membrane, and cell-to-cell recognition.There are 20 to 40 % lipids and 60 to 80 % proteins in plasma membrane .

What is plasma membrane made of?
The plasma membrane is a lipid bi layer. It consists of phospolipids which have hydrophillic heads and hydrophobic tails. The heads form the outer part of the bi layer and the tails are sandwiched between the heads. Thus the surfaces of the bi layer are hydrophillic and the inner part is hydrophobic. The phospholipids are arranged in a mosaic pattern and the structure of plasma membrane is often referred to as a fluid mosaic. It is called fluid because the phospholipids can move about in the layer. Besides the phospholipids, the plasma membrane also consists of lipoproteins, porins, glycoproteins and other molecules adhered to or as part of it. The hydrophobic and hydrophillic nature of the plasma membrane offers it semi-permeability, that is, the membrane allows passage of only certain molecules.
