BRAINCAKEGolgi Apparatus
The Golgi Apparatus is a stack of flattened sacs called cisternae.
Vesicles bud off from the rough ER are directed along the cytoskeleton to the Golgi and fuse with the cis face of the Golgi.
The Golgi modifies these proteins, for example, by adding carbohydrate chains to form glycoproteins.
