Detailed explanation-1: -The outer lining of a eukaryotic cell is called the plasma membrane. This membrane serves to separate and protect a cell from its surrounding environment and is made mostly from a double layer of proteins and lipids, fat-like molecules.

Detailed explanation-2: -The cell membrane acts like a filter allowing necessary materials in and waste out, while keeping the organelles and cytoplasm in.

Detailed explanation-3: -The plasma membrane of the cell defines the cell boundary.

Detailed explanation-4: -The Cellular Membrane 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.
