NEET BIOLOGY

Detailed explanation-1: -Final answer : The plasma membrane is the boundary of the cell, made up of lipids and proteins, and controls the substances entering or leaving the cell.

Detailed explanation-2: -The outer boundary of the cell is called the cell membrane, or plasma membrane. The cell membrane is one of the most important organelles in the cell, and all cells have a cell membrane. It not only separates the cell from the environment, but also regulates what comes in and out of the cell.

Detailed explanation-3: -With few exceptions, cellular membranes-including plasma membranes and internal membranes-are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains. Glycerol is a three-carbon molecule that functions as the backbone of these membrane lipids.

Detailed explanation-4: -Lipid phase boundaries Phase separation creates a compositional phase boundary with a unique status: the phase boundaries are the physical sites at which the membrane properties change abruptly. Cells can use the sharp differences in membrane properties to colocalize some components and to separate others.

Detailed explanation-5: -Cell Membrane (Plasma Membrane) The cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable.
