Membranes
The plasma membrane is the unique membrane surrounding the cell, but a single membrane cannot be resolved with the light microscope. Therefore, the line visible between adjacent cells represents the plasma membranes of both cells, as well as intercellular space, cytoskeletal elements, and proteins associated with the membrane.
