Detailed explanation-1: -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. The cell membrane regulates the transport of materials entering and exiting the cell.

Detailed explanation-2: -Why it is called a plasma membrane? The cell contains a protoplasm (or simply plasm), which is the semi-fluid living matter. This living matter or plasm is contained inside a biological membrane referred to as the plasma membrane.

Detailed explanation-3: -The cell membrane is also called the plasma membrane and is made of a phospholipid bilayer. The phospholipids have a hydrophilic (water attracting) head and two hydrophobic (water repelling) tails. The head of a phospholipid is made of an alcohol and phosphate group, while the tails are chains of fatty acids.

Detailed explanation-4: -While cell membrane covers the entire components of a cell, plasma membrane covers only the cell’s organelles. Some main differences between the two are the fact that the plasma membrane encloses the organelles, whereas the cell membrane encloses the entire cell.

Detailed explanation-5: -Both prokaryotic and eukaryotic cells have a plasma membrane, a double layer of lipids that separates the cell interior from the outside environment. This double layer consists largely of specialized lipids called phospholipids.
