The advantage gained by eukaryotic cells by evolving elaborate internal membrane systems for importing substances from the outside. Introduction Eukaryotic cells have internal compartmentalization. These internal compartments have their own division of labor. Eukaryotic cells perform two unique functions such as exocytosis and endocytosis. Endocytosis is the process where the cell takes in contents from the extra cellular environment and encloses it in a vesicle. The vesicle obtains the lipid bilayer from the plasma membrane by pinching off from the plasma membrane towards the interior of the cell along with the extracellular components entrapped inside. Exocytosis is the reverse process wherein the vesicles merge with the plasma membrane after pinching off from the Golgi complex in order to discharge the contents entrapped to the exterior of the cell.
