Name ___________________________________ Date ______________ Per ____ Cell Membrane Structure and Function Composition of the Cell Membrane & Functions The cell membraneis also called the plasma membrane and is made of a phospholipid bilayer (A). Some of the functions of the cell membrane include protecting and enclosing the cell, giving shape to the cell, allowing transportation of materials in and out of the cell, and carry out metabolic reactions near the inner surface of the cell membrane. The phospholipids of the cell membrane have a hydrophilic(water loving/attracting) head (G) and two hydrophobic(water fearing/repeling) tails (F). The head of a phospholipid is made of an alcohol and phosphate group, while the tails are chains of fatty acids. The cell membrane is constantly vibrating, creating small openings within the structure. Therefore, the phospholipids can allow water and other smaller molecules to pass through into or out of the cell, without the use of energy. This type of passive transport is known as
