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.

Thylakoids are the membranous system in the chloroplast. Cristae are the infoldings in the inner membrane of mitochondria. Cisternae are the disc shaped sacs in the Golgi
apparatus. Chromatin is the condensed structure of DNA in the nucleus.
