Question
Chapter 5.3, Problem 1RIA
Summary Introduction
The plasma membrane is also called a cell membrane or cytoplasmic membrane. It is a network of protein and lipids that form the boundary among the outside of the cell and contents of cells. The major function of the plasma membrane is to protect the cell from its surrounding environment.
