The Golgi apparatus
Golgi apparatus, also
known as the Golgi complex
Golgi body, or simply the
Golgi, is an organelle found
in most eukaryotic cells.
Golgi was identified in
1897 by the Italian
physician Camillo Golgi.
This cell organelle was
named after him in 1898.
The Golgi structure
1. Is a smooth, curvy structure.
2. Has a flattened stack of membranes.
3. Has a front end and a back end.
4. The front end is called the cis face
cis face and
the back end is called the trans face
The basic function of the Golgi apparatus is the
transport of proteins within the cell.
The Golgi receives materials for transportation
through the cis face
cis face and sends the materials
through to the trans face
trans face once they are packaged
and modified into the vesicles.
It functions in the collection, packaging, and
distribution of material.
Cisternae are the
flattened membrane folds
of the Golgi apparatus that push
together, pinching off secretory
vesicles containing molecules;
which are then discharged into
Golgi apparatus is a major collection
and dispatch station of protein products

Proteins synthesized in the ER are
packaged into vesicles, which then fuse
with the Golgi apparatus.
In this respect, the Golgi can be
thought of as similar to a post
office: it packages and labels items
which it then sends to different
parts of the cell or to the
The Golgi apparatus is also
involved in lipid transport and
The vesicles that leave the rough ER are
transported to the cis face of the Golgi
apparatus, where they fuse with the Golgi
membrane and empty their contents into
Once inside the lumen, the molecules are
modified, then sorted for transport to their
