3. Golgi apparatus

• Structure
• Consist of flattened cavities called cisternae
  lined with smooth endoplasmic reticulum
• Numerous vesicles containing secretory granules
  are pinched off at the edges
• Formation
• Formed by the fusion of vesicles pinched off from
  the cavities of ER

• Functions
• Site for concentrating and packing the materials
  in other parts of the cell e.g. proteins newly
  synthesized in the rough ER are transported in
  the vesicles to the Golgi apparatus where
  carbohydrates are added to form glycoproteins
  which are then packed in vesicles for discharge
• May play a part in primary wall formation
• Lipid transport
• Lysosome formation
