- The cell membrane (also known as the plasma membrane or cytoplasmic membrane) is a biological membrane that separates the interior of all cells from the outside environment. The cell membrane is selectively permeable to ions and organic molecules and controls the movement of substances in and out of cells.The basic function of the cell membrane is to protect the cell from its surroundings. It consists of the phospholipid bilayer with embedded proteins.. Exocytosis: Just as material can be brought into the cell by invagination and formation of a vesicle, the membrane of a vesicle can be fused with the plasma membrane, extruding its contents to the surrounding medium. This is the process of exocytosis.

The plasma membrane of a muscle cell is called what? Answers. Relevance. Rating Newest Oldest. Best Answer: The sarcolemma is the cell membrane of a muscle cell. It consists of a true cell membrane, called the plasma membrane, and an outer coat made up of a thin layer of polysaccharide material that contains numerous thin collagen fibrils.t each end of the muscle fiber, this surface layer of the sarcolemma fuses with a tendon fiber, and the tendon fibers in turn collect into bundles to form the muscle tendons that then insert into bones. The membrane is designed to receive and conduct stimuli. Source(s): Tinker · 8 years ago.

Why is the plasma membrane sometimes referred to as the fluid mosaic model?   The plasma membrance is a mosaic model-thus named because the constituent molecules of the membrane, e.g. phospholipids, cholesterol, proteins, exist in a state of tigh … t associations and fluidity.he membrane is a bilayer of phospholipids. Because the tails are hydrophobic they interact with each other and occupy the inner membrane away from water. The polar heads are … the exterior and interior of the membrane since they interact well with water.

- Plasma Membrane. All living cells, prokaryotic and eukaryotic, have a plasma membrane that encloses their contents and serves as a semi-porous barrier to the outside environment. The membrane acts as a boundary, holding the cell constituents together and keeping other substances from entering.The plasma membrane is permeable to specific molecules, however, and allows nutrients and other essential elements to enter the cell and waste materials to leave the cell.he presence of cholesterol and glycolipids, which are found in most cell membranes, can also affect molecular dynamics and inhibit phase transitions. In prokaryotes and plants, the plasma membrane is an inner layer of protection since a rigid cell wall forms the outside boundary for their cells.

Plasma Membrane of a Cell: Definition, Function & Structure The plasma membrane is the boundary between the cell and its environment. It regulates what enters and exits the cell. Cells must maintain an appropriate amount of molecules to function inside them. They must also have a way to keep things out or to allow things to enter. This is the job of the plasma membrane.

You are made up of trillions and trillions of cells, and each one is separated A cell is the basic unit of life, and all organisms are made up of one or many cells. One of the things that all cells have in common is a cell membrane. It is a barrier that separates a cell from its surrounding environment. This outer boundary of the cell is also called the plasma membrane.his ensures that the cells will be able to get rid of wastes and take up important nutrients and gases. The plasma membrane is a fluid mosaic. This means that it is flexible and made up of many different types of molecules. Phospholipids form the basic structure of a cell membrane, called the lipid bilayer.

- 1 Plasma Membrane-Membrane surrounding the cytoplasm that consists of a phospholipid bilayer with embedded proteins; functions to regulate the entrance and exit of molecules from cell. Phospholipids-Molecule having the same structure as a neutral fat except one bonded fatty acid is replaced by a group that contains phosphate; an important component of plasma membranes.

Cell membrane The cell membrane (or plasma membrane or plasmalemma) surrounds the cytoplasm of living cells, physically separating the intracellular components from the extracellular environment.he cell membrane consists of three classes of amphipathic lipids: phospholipids, glycolipids, and sterols. The amount of each depends upon the type of cell, but in the majority of cases phospholipids are the most abundant. In RBC studies, 30% of the plasma membrane is lipid.

The plasma membrane (also known as the cell membrane) is the outermost cell surface, which separates the cell from the external environment. The plasma membrane is composed primarily of proteins and lipids, especially phospholipids. The lipids occur in two layers (a bilayer).

Be Part of Ask A Biologist The lipids that are present in the plasma membrane are called phospholipids.. These lipid layers are made up of a number of fatty acid building blocks. The fatty acid that makes up this membrane has two different parts to it-a small water loving head-hydrophilic head.Hydro stands for water and philic means liking or loving.hannels/pores-A channel in the cell's plasma membrane. This channel is made up of certain proteins whose function is to control the movement of food and water into the cell. These channels are made up of certain proteins.

What is the difference between the plasma membrane and the cell membrane? Most textbooks are likely to use the two terms interchangeably (as the outer membrane surrounding living cells), but you might find sources that say that the plasma membrane is the outer membrane (surrounding the cytoplasm), but both the plasma membrane and membranes surrounding organelles inside the cell are called cell membranes.
