A diagram of a plasma membrane shows a phospholipid bilayer with 3 proteins embedded in the bilayer. One of the proteins is shown with a channel in it. The 3 proteins have lines with the label integral membrane proteins. On the inner side of the phospholipid bilayer is another protein that is positioned up against the inner portion of the bilayer.
Mar 26, 2019 · 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 also simply called the cell membrane. The main function of the plasma membrane is to protect the cell from its … labeled

Plasma membrane and cytoplasm (article) | Khan Academy
The plasma membrane is the border between the interior and exterior of a cell. As such, it controls passage of various molecules—including sugars, amino acids, ions, and water—into and out of the cell. How easily these molecules can cross the membrane depends on their size and polarity.
The fluid mosaic model describes the structure of the plasma membrane as comprised of diverse components—including phospholipids, cholesterol, proteins, and carbohydrates—that are able to flow and change position, while maintaining the basic integrity of the membrane.

Structure of the Plasma Membrane - The Cell - NCBI Bookshelf
Like all other cellular membranes, the plasma membrane consists of both lipids and proteins. The fundamental structure of the membrane is the phospholipid bilayer, which forms a stable barrier between two aqueous compartments. In the case of the plasma membrane, these compartments are the inside and the outside of the cell.

Feb 2, 2023 · The cell membrane, also called the plasma membrane, is a thin layer that surrounds the cytoplasm of all prokaryotic and eukaryotic cells, including plant and animal cells. It is a selectively permeable cell organelle,allowing certain substances inside the cell while preventing others to pass through and thus is analogous to a barrier or ...
