Plasma membrane function
Chapter #7 – Membrane Structure And Function
The plasma membrane separates the living cell from its surroundings. This thin barrier, 8 nm thick, controls traffic into and out of the cell. Like all biological membranes, the plasma membrane is selectively permeable, allowing some substances to cross more easily than others.

The Cell Membrane. Plasma membrane. is the boundary that separates cells from their environment. Its function is to regulate what enters and leaves the cell. The plasma membrane displays a property known as _____ permeability. Selective permeability means that only _____ substances are allowed to pass through the membrane.
Plasma Membrane - Definition, Structure, Functions ...
Mar 26, 2019 · Plasma Membrane Definition. The plasma membrane of a cell is a network of lipids and proteins that forms the boundary between a cell’s contents and the outside of the cell. It is also simply called the cell membrane.The main function of the plasma membrane is to protect the cell from its surrounding environment.
