there are four main parts of the plasma membrane of a cell.
1) the lipid bilayer: this is made up of amphipathic molecules, with the polar heads on the outsides and the non polar tails in the middle. this part is semi-permeable.
2) the proteins: these work as canals to pump larger molecules through the bilayer which couldn't otherwise fit.
3) the carbohydrates: these are different on each cell and are used as the "chemical id tag" for identifying other cells.
4) the cholesterol: this is used to keep the lipid bilayer as plasma instead of turning into a solid.
hope this helps (:

Another name for plasma membrane?
A cell membrane is also known as a plasma membrane or cytoplasmic membrane. The cell membrane separates the interior of a cell from its outside environment. The main function of a cell membrane is to protect the cell from its surroundings.
Which organelle is responsible for renewing and modifying the plasma membrane?
The organelle responsible for renewing and modifying the plasma membrane is the Golgi apparatus. It processes, sorts, and packages lipids and proteins for transport to the plasma membrane, where they can be incorporated into its structure. Additionally, the Golgi apparatus plays a crucial role in glycosylation and other modifications that affect membrane composition and function.
