What is the phospholipid bilayer also known as?
The lipid bilayer (or phospholipid bilayer) is a thin polar membrane made of two layers of lipid molecules. These membranes are flat sheets that form a continuous barrier around all cells.
Is phospholipid another name for cell membrane?
Phospholipids, arranged in a bilayer, make up the basic fabric of the plasma membrane. They are well-suited for this role because they are amphipathic, meaning that they have both hydrophilic and hydrophobic regions.

| What is the only job the the cell membrane? | Maintain homeostasis by controlling what an enter and leave the cell. |
Why is it called a phospholipid bilayer?
The structure is called a “lipid bilayer” because it is composed of two layers of fat cells organized in two sheets.
What is another name for the plasma membrane?
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.
What are integral proteins also called?
Integral membrane proteins, also called intrinsic proteins, have one or more segments that are embedded in the phospholipid bilayer.
How do you name phospholipids?
To name the phospholipid completely in the trivial system, we must provide: (a) the trivial names of the fatty acyl chains (with an -oyl ending); and (b) the name of the polar alcohol which is joined to the phosphoryl group.
Why do phospholipids form a bilayer in plasma membranes?
Why do Phospholipids form bilayers? -Phospholipids are amphipathic with a hydrophilic phosphate group and one or two hydrophobic hydrocarbon tails. – They form bilayers because the hydrophobic hydrocarbon tails will be shielded from interacting with water and will form noncovalent interactions.
What are 4 other names for the cell membrane?
The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane, and historically referred to as the plasmalemma) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment.

What is the other name for cell membrane?
plasma 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. In bacterial and plant cells, a cell wall is attached to the plasma membrane on its outside surface.
What does selectively permeable mean?
Biology definition: A selectively-permeable membrane is a membrane that allows only some substances and molecules to pass into or leave the cell.
