Detailed explanation-1: -The plasma membrane is composed mainly of phospholipids, which consist of fatty acids and alcohol. The phospholipids in the plasma membrane are arranged in two layers, called a phospholipid bilayer, with a hydrophobic, or water-hating, interior and a hydrophilic, or water-loving, exterior.

Detailed explanation-2: -The correct answer is cell membrane.

Detailed explanation-3: -The cell wall is the structure that surrounds the cell membrane and gives support to the cell. The cell wall provides tensile strength as well as protection to the cell.

Detailed explanation-4: -The plasma membrane is made up primarily of a bilayer of phospholipids with embedded proteins, carbohydrates, glycolipids, and glycoproteins, and, in animal cells, cholesterol.

Detailed explanation-5: -Phosphoglycerides (also known as glycerophospholipids) are the most abundant phospholipids in cell membranes.
