ANATOMY

Detailed explanation-1: -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. The primary function of the plasma membrane is to protect the cell from its surroundings.

Detailed explanation-2: -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.

Detailed explanation-3: -Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in.

Detailed explanation-4: -Those proteins are either glycoproteins, meaning there are sugar and a protein moiety, or they can be lipid proteins, meaning that there are fat and a protein. And those proteins which stick outside of the plasma membrane will allow for interaction of one cell with another cell.

Detailed explanation-5: -Cell membranes act as a barrier and gatekeeper between two distinct areas. Due to their semi-permeable nature, only a small number of molecules may penetrate the lipid bilayer. Gas and small hydrophobic molecules, such as oxygen and and carbon dioxide can quickly pass through membranes.
