The plasma membrane is composed of lipids that are arranged in a bilayer. Also, the lipids are arranged within the membrane with the polar head towards the outer sides and the hydrophobic tails towards the inner part. The membrane proteins can be classified as integral or peripheral. Peripheral proteins lie on the surface

Proteins embedded in a phospholipids layer
The plasma membrane, also known as the cell membrane, is primarily composed of a phospholipid bilayer with embedded proteins. This structure plays a crucial role in maintaining the integrity of the cell and regulating the passage of molecules in and out of the cell.
Phospholipid Bilayer:
- The phospholipid bilayer consists of two layers of phospholipid molecules, with hydrophilic (water-loving) heads facing outward and hydrophobic (water-fearing) tails facing inward.
- This arrangement creates a barrier that separates the internal environment of the cell from the external environment.
Embedded Proteins:
- Proteins are embedded within the phospholipid bilayer, with some proteins extending across the entire membrane (integral proteins) and others attached to only one side of the membrane (peripheral proteins).
- These proteins serve various functions such as transport of molecules, cell signaling, and cell adhesion.
Importance of the Plasma Membrane:
- The plasma membrane is essential for maintaining cell structure and protecting the internal components of the cell.
- It regulates the passage of molecules in and out of the cell, allowing for selective permeability.
- The proteins embedded in the membrane play a crucial role in cell communication and signaling.
In conclusion, the plasma membrane consists mainly of phospholipids with embedded proteins that work together to ensure the proper functioning of the cell.
