    Study Notes

    Cell Membrane Basics

    • The primary function of the cell membrane is to regulate what enters and leaves the cell.

    Cell Membrane Structure

    • The average thickness of cell membranes is 7.5-10 nanometers.

    Cell Membrane Function

    • The cell membrane, also known as the plasma membrane, allows certain substances to pass through from the outside through a process called selective permeability.
    • The cell membrane provides a platform for cell interactions, such as cell signaling and adhesion.
