Function of the Plasma Membrane Biology Review (Video)
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.

Here we'll describe general features of membranes, using the plasma membrane as our example. A. The Phospholipid Bilayer. Gorter and Grendel predicted the bilayer membrane structure as early as 1925. They knew that red blood cells (erythrocytes) have no nucleus or other organelles, and thus have only a plasma membrane.
Structure Of Plasma Membrane Diagram / Components And Structure
The endomembrane system ( endo - = "within") is a group of membranes and organelles in eukaryotic cells that works together to modify, package, and transport lipids and proteins. It includes a variety of organelles, such as the nuclear envelope and lysosomes, which you may already know, and the endoplasmic reticulum and Golgi apparatus.

The plasma membrane (also known as the cell membrane or cytoplasmic membrane) is a biological membrane that separates the interior of a cell from its outside environment. It is a fluid mosaic of lipids, proteins and carbohydrate. The plasma membrane is impermeable to ions and most water-soluble molecules. They cross the membrane only through.
STRUCTURE of PLASMA MEMBRANE
The plasma membrane is a flexible, lipid bilayer that surrounds and contains the cytoplasm of the cell. Based on their arrangement of molecules and the presence of certain specialized components, it is also described as the fluid mosaic model.

Just 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. This cell membrane provides a protective barrier around the cell and regulates which materials can pass in or out.

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 surrounding environment.
The Plasma Membrane Structure Anatomy & Physiology
This membrane has about the consistency of.salad oil 1 . The first time I read that factoid, I didn't find it very reassuring! Salad oil seems like an awfully fragile boundary to place between a cell and the rest of the world. Luckily, the plasma membrane turns out to be very well-suited to its job, salad oil texture and all.
Plasma membrane Basic structure, composition and Function
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.

Key Points. The principal components of the plasma membrane are lipids ( phospholipids and cholesterol), proteins, and carbohydrates. The plasma membrane protects intracellular components from the extracellular environment. The plasma membrane mediates cellular processes by regulating the materials that enter and exit the cell.

The cell membrane is primarily made up of three things: 1. Phospholipids 2. Cholesterol 3. Proteins 1) Phospholipids There are two important parts of a phospholipid: the head and the two tails. The head is a phosphate molecule that is attracted to water ( hydrophilic ).
