The Golgi apparatus (also called the Golgi complex) is an important organelle in eukaryotic cells. The Golgi apparatus further modifies many proteins and lipids from the endoplasmic reticulum. Afterwards they get transfered to different places within or outside the cell.
History
The Golgi apparatus is named after it's discoverer Camillo Golgi who discovered it in 1898.
Composition
It's morphology varies considerably between different cell types. In higher eukaryotic cells the Golgi apparat usually consists of three to ten cisternaes of around 1*10^-6m diameter which are arranged as a stack. Those cisternaes are flattend which leads to a high surface-to-volume ratio which could facilitate the activity of the enzymes inside the Golgi apparat.
Function
Through adding certain signal oligosaccharides a protein can be tagged to be transported to a specific area of the cell.
