Cell Membrane Structure and Function Quiz

The cell membrane consists of a double layer of phospholipids called the phospholipid bilayer. Each phospholipid molecule has a hydrophilic (water-attracting) head and two hydrophobic (water-repelling) tails.

The cell membrane acts as a barrier, controlling the movement of substances in and out of the cell, allowing for selective permeability. It is involved in cell signaling, cell adhesion, and contains proteins for enzymatic activity and transport of molecules.

The cell membrane contains receptors that can receive signals from other cells or molecules, allowing for communication and coordination between cells.
