Cell Membrane
The entire cell is surrounded by a thin membrane.
Function controls which substances pass into and
out of the cell. SELECTIVELY PERMEABLE
5
(Cell membrane continued)
Structure composed of phospholipids and proteins
in a double layer or bilayer.
6
(Cell membrane continued)
Floating around in the cell membrane are
different kinds of proteins. They are not held in
any fixed pattern but instead float around in the
phospholipid layer.
This model is called the fluid mosaic model. The
positions of the lipids and proteins is
constantly changing.
