The Golgi apparatus is an internal organelle found near the nucleus of a eukaryotic cell. It is a stack of membrane-enclosed sacs called cisternae. Each stack contains 3-20 cisternae. The stack consists of the inner cis face and the outer trans face. Molecules synthesised in the Endoplasmic Reticulum enter the inner cis face via vesicles. Within the Golgi apparatus oligosaccharide groups are attached to the molecules. Molecules leave the Golgi via vesicles through the outer trans face and are transported to organelles or the plasma membrane [1].
