Give examples of polarized cells that cell membrane differs compositionally,

-Epithelial cells have apical lateral and basal pole, who differ and might share some structural characteristics. Apical pole (transporters, absorption) Basal pole (adhesion transportation to CT) lateral pole (adhesion) -Hepatocytes: three different poles, each with contact to two neighboring cells and bile canaliculus (site of bile secretion) one pole faces capillary sinusoids, various nutreints are exchanged with blood stream, thus it has receptors transporters enzymes...Second pole is adjacent to neighboring cells, exchange of substances and desmosomes junctions. Third pole in contact with bile canaliculus into which bile and salt pigments are inserted.
