In 1898, Camillo Golgi, an Italian physician discovered the Golgi apparatus in cells. Golgi apparatus consists of a stack of slightly curved saccules.
The Golgi apparatus is the cell’s refining, packaging, and shipping center, as it modifies many cellular products and prepares them for export (refines, packages, and ships macromolecular products).
The Golgi apparatus receives substances, (proteins and lipids) from the ER, refines them into final products, packages proteins and lipids into vesicles (membrane-bound storage and shipping containers) for secretion or movement into other parts of the cell.
During the modification process, it adds carbohydrate labels to proteins or alters new lipids in different ways.
