Cell membrane definition quizlet. This is the currently selected item. While the terms cell membrane and plasma membrane are used interchangeably in some books, there is a slight difference between the two. Definition noun a membrane that is selectively permeable, i.e.
To learn more about the skin of a cell, review the corresponding lesson plasma membrane of a cell: The cell membrane is the only membrane involved in cytokinesis.

So if we have a very basic picture of a cell here with a little nucleus on the inside, this pink outside layer is what we call the cell membrane.
When an extracellular solution has the same concentration of solute as that inside the cell, the solution is termed an isotonic solution. Cell membranes protect and organize cells. This structure has two layers, and is represented in the diagram below.
