Like all other cellular membranes, the plasma membrane consists of both lipids and proteins. Web plasma membrane stains are one of the most important organelle markers for unambiguous assignments of individual cells and monitoring membrane morphology and dynamics. The primary function of the plasma membrane is to protect the cell from its surroundings. Using a range of resources including;

In The Following Schematic Drawing Of An Abundant Plasma Membrane Phosphoglyceride, Which Part Is Positively Charged?

Relate structures of the cell membrane to its functions. A plasma membrane is mainly composed of carbohydrates, phospholipids, proteins, and conjugated molecules, and it is about 5 to 8 nm in thickness. Web according to the fluid mosaic model, the plasma membrane is a mosaic of components—primarily, phospholipids, cholesterol, and proteins—that move freely and fluidly in the plane of the membrane.

Basic Cell And Molecular Biology (Bergtrom) 16:

Web as the outer layer of your skin separates your body from its environment, the cell membrane (also known as the plasma membrane) separates the inner contents of a cell from its exterior environment. By the end of this section, you will be able to: Web the plasma membrane of a cell is a network of lipids and proteins that forms the boundary between a cell’s contents and the outside of the cell. It is the membrane found in all cells, that separate the inner part of the cell from the exterior.
