The endomembrane system organelle that is responsible for sorting endomembrane system-associated materials for movement about the cell.

The Golgi apparatus consists of a series of flattened endomembrane "bags", called cisternae, that both receive vesicles from the endoplasmic reticulum (cis face) and transmit vesicles (from the trans face) to the rest of the cell.

Part of what the Golgi apparatus sorts are proteins translated in association with the rough endoplasmic reticulum. These include membrane proteins, to be secreted proteins, and proteins destined to be located with the lumen of various endomembrane system members. In addition to sorting proteins, the Golgi also is involved in the sorting of lipids, which are synthesized in association with the smooth endoplasmic reticulum
