The structure of a cell membrane is designed to keep the internal contents of the cell intact, as well as keep unneeded materials out. The membrane is made up of a number of holes through which chemical processes and material exchanges take place.
Answers: The cell membrane is composed of a phospholipid bilayer. Facing both the extra and cytoplasmic sides of the cell are the hydrophilic heads. The hydrophobic tails of the phospholipids are clustered inside. Various proteins, sterols (e.g. cholesterol), lipids and carbohydrates are embedded in the plasma membrane.Some are peripheral, and are only one side of the membrane. Others are transmembrane. The cell membrane has various functions: Provides a semipermeable barrier for the cell from the outside world.nswers: The cell membrane is composed of a phospholipid bilayer.
