Interior Cell Membranes. It is the thick and rigid structure with a fixed shape. The cell membrane consists of a lipid bilayer that is semipermeable.
The nuclear membrane the endoplasmic reticulum the Golgi apparatus lysosomes vesicles endosomes and plasma membrane among others. The cell membrane also called the plasma membraneplasma membrane or plasmalemmaplasmalemma is a biological membrane separating the interior of a cell from the outside environment It appears in thin sections with the electron microscope as a triple-layered structure about 7510 nanometers thick Term coined by C. The membrane of an internal vesicle fuses with the external plasma membrane and the internal contents of the vesicle are expelled to the outside.
These membranes divide the cell into functional and structural compartments or organelles.
The heads which form the outer and inner linings are hydrophilic water loving while the tails that face the interior of the cell membrane are hydrophobic water fearing.

Unlike prokaryotes eukaryotic cells also possess internal membranes that encase their organelles and control the exchange of essential cell components. In contrast the interior of the cell membrane is hydrophobic and will not interact with water.
