Often described as a phospholipid bilayer, for 10 points, name this barrier between the cell and its outside environment.
This structure contains several members of the ABC protein family, and another major component of these objects is a derivative of sphingosine. Singer and Nicholson developed the fluid mosaic model of this structure. Clathrin-coated pits in it are involved in endocytosis, and specialized areas of this structure include tight junctions and gap junctions. In plants this structure is surrounded by the cell wall.
