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. A plasma membrane, by definition, is a fluid, phospholipid bilayer that separates the interior of all cells (prokaryotic, eukaryotic, animal and plant) from their external environment and plays a key role in many cellular processes. This membrane is what controls the movement of substances into and out of the cell, but it is selectively permeable. The Plasma membrane is considered to conform to the fluid mosaic model of the cell membrane proposed by singer and Nicholson.

The green molecules in Figure below, for example, are the lipid cholesterol. Molecules of cholesterol help the plasma membrane keep its shape. Many of the proteins in the plasma membrane assist other substances in crossing The plasma membrane H+ - ATPase or proton pump creates the electrochemical gradients in the plasma membrane of plants, fungi, protists, and many prokaryotes. Here, proton gradients are used to drive secondary transport processes.

The plasma membrane is a selectively permeable membrane, which permits the movement of only certain molecules both in and out of the cell. The plasma membranes play an important role in both the endocytosis and exocytosis process.

Plasma Membrane (Cell Membrane) The plasma membrane, also called the cell membrane, is the membrane found in all cells that separates the interior of the cell from the outside environment.

The plasma membrane is composed primarily of proteins and lipids in all cases. The plasma membrane is seen as a thin wavy line around the surface of the protoplast under the electron microscope. The tripartite structure of the plasma membrane with dark-light-dark structures can be seen at higher magnification.

Functions of Plasma Membrane. The primary function of the plasma membrane is to protect the cell from its surroundings. The plasma membrane also plays a role in anchoring the cytoskeleton to provide shape to the cell, and in attaching to the extracellular matrix and other cells to help group cells together to form tissues. Se hela listan på scienceabc.com The plasma membrane, or cell membrane, consists of a lipid bilayer which separates the interior of the cell from the exterior. The membrane is composed of phospholipids, cholesterol, glycolipids, and a large fraction of membrane proteins, organized together in different domains. Morphology of Plasma Membrane: The plasma membrane is not easily visible under a light microscope. The electron microscope displays that the plasma membrane is 6 nm to 10 nm thick.
