The Golgi Apparatus - Practice Questions & MCQ

Components of the Endomembrane System: The Golgi Apparatus

• It is a stack of membranous bodies called cisternae. It was discovered by Camillo Golgi, an Italian physicist, in 1897. 
• These are present in both plant cells and animal cells. In-plant cells, they occur as unconnected units called dictyosomes. 
• Like the endoplasmic reticulum, they are also made up of tubules and vesicles apart from cisternae.
• The face of the Golgi apparatus that receives vesicles from the ER is called a cis face. 
• The opposite of cis face is the trans face which gives off vesicles for the destination. 
   

• The Golgi apparatus is primarily involved in the processing of proteins generated in the endoplasmic reticulum. 
• It is also responsible for their transport to the different parts of the cell. 
• The Golgi apparatus functions as a platform for the process of addition of sulfate groups into protein molecules, glycosylation and phosphorylation.
