BRAINCAKEGolgi Apparatus
The Golgi apparatus (Golgi body) is a stack of flattened, curved, membrane-bound sacs called cisternae, with many small vesicles around its edges. Unlike the ER, the sacs are not connected to one another.
The Golgi apparatus has two faces. Vesicles from the rough ER arrive and fuse with the cis face (the forming face), which is nearer the ER. Vesicles leave from the opposite trans face (the maturing face).
