And Composition of the Cell Membrane & Functions
The cell membrane is also called the
membrane and is made of a phospholipid
The
phospholipids have a hydrophilic (water attracting).
two hydrophobic (water repelling).
The head of a
phospholipid is made of an alcohol and
group, while the
tails are chains of
Phospholipids can move
and allow water and other
molecules
to pass through into or out of the cell. This is known as simple
because it does not require
and the
water or molecules are moving
the concentration
gradient. SKETCH AND LABEL a phospholipid coloring the heads red
and the tails blue.
