Unlike the cell wall, the cell membrane is flexible and its shape can be changed as needed. Also, it is metabolically active and has selective permeability. 1.
How do cell walls differ from cell membranes?
The difference between the cell wall and the cell membrane is primarily due to the differences in three factors like composition, function and permeability. The cell wall composition mainly comprises proteins and carbohydrates, whereas a cell or plasma membrane comprises lipids, proteins, and some amount of carbohydrate.

How is the cell membrane formed?
The lipid bilayer is considered as a two-dimensional liquid, where the lipid and protein molecules are diffused more or less easily in it. It is formed during self-assembly of lipid molecules. These lipids are amphipathic phospholipids. Their hydrophobic “tail” regions are hidden from the surrounding water or the hydrophilic environment by the bilayer structure. Thus, hydrophilic heads interact with either intracellular/cytosolic or extracellular faces. By this, a continuous, spherical lipid bilayer is formed. Therefore, hydrophobic interactions are considered as major driving forces for the lipid bilayer formation.

What is a Cell Wall?
Cell wall is the outermost layer of many cells except in animal cells. Bacteria, plants, fungi and most protists contain a cell wall surrounding the cell membrane of their cells. Structurally, it is a rigid layer that provides a definite shape to the cell. However, the composition of the cell wall differs among the different organisms. Peptidoglycan is the main compound that is present in the bacterial cell wall. In contrast, chitin is the main component present in the fungal cell wall. Plant cell wall contains cellulose as its main compound. Likewise, the main compound that gives a characteristic feature to their cell wall differs between the groups of the organisms and facilitates the easy identification.
What is a Cell Membrane?
Cell membrane or plasma membrane is a selectively permeable layer present in all most all cell types. It encloses the cell and separates its content from the outer environment. Moreover, it is a flexible membrane, which is about 5 to 10 nm thick. Structurally, it is a phospholipid bilayer. Apart from the two leaflets of the phospholipid molecules, two types of protein molecules are also present in the cell membrane. They are integral proteins and peripheral proteins. Among these two types, integral proteins permanently attach with the phospholipid layer while the peripheral proteins temporally attach with the phospholipid layer. Some integral proteins are transmembrane proteins that span across the phospholipid bilayer. The “fluid mosaic model” is the model that nicely describes the above-mentioned structure of cell membrane.
