Cell membrane is made of protein lipid bilayer which contains transmembrane protein(i.e. intrinsic protein) and the extrinsic protein.The lipid bilayer contains a hydrophilic polar head and a hydrophobic non-polar tail.
The composition of the cell wall includes:
1. Deposited materials: which include hemicellulose, pectin, chitin, lignin, suberin,etc.
2.Matrix:which includes protein, lipid and water.
3.Structural:which contains macrofibrils.
