3. INTRODUCTION
• The Golgi apparatus also known as the Golgi body and
Golgi complex.
• It is a organelle found in most Eukaryotic cell.
• The Golgi apparatus is made up of a stack of membrane-
bound bodies known as the cisternae.
• It stores and modify proteins for specific functions and
prepare them for transport to other parts of the cell.

4. DISCOVERY
• It was identified in 1897 by the Italian
scientist Camillo Golgi and named after
him in 1898.
• He developed the staining method known
as Golgi staining.
• This method stained the Golgi complex
intensely and made possible the
demonstration of its occurrence in a wide
verify of cell types.

5. STRUCTURE
• Golgi apparatus composed of stacks of membrane-bound
structures known as Cisternae.
• Cisternae is a flattened membrane disk of the Golgi
apparatus.
• Golgi Apparatus usually has 6-7 cisternae.
• Golgi Apparatus have Three compartments in structure.
Cis face
Lumen
Trans face

6. Structure Of Golgi Apparatus

7. Cis-face:
• It present near the Endoplasmic reticulum
• It is a compartment where vesicles enters into the Golgi
Apparatus.
• Also known as Receiving Department of Golgi Apparatus.
Lumen:
• Lumen have the enzymes to modify the carbohydrate portion
of glycoprotein.
• It is a processing compartment.
Trans-face:
• It is a compartment where vesicles exit from the Golgi
Apparatus.
• It is also known as Shipping Department of Golgi
Apparatus.

9. FUNCTIONS
• The cell synthesize a huge amount of variety of macromolecules.
The main function of the Golgi apparatus is to modify, sort
and package the macromolecules that are synthesized by the
cells.
• It mainly modifies the proteins that are prepared by the
endoplasmic reticulum.
• They are also involved in the transport of lipid molecules
around the cell and also formation of lysosomes.
• The Golgi complex also plays an important role in the
production of proteoglycans.
