Class 11 Biology Cell : The Unit of Life Golgi apparatus

Golgi apparatus

  • Structures consist of many flat, disc-shaped sacs or cisternae of 0.5μm to 1.0μm diameter, which are stacked parallel to each other are called Golgi apparatus.
  • Camillo Golgi (1898) first observed Golgi apparatus.
  • The Golgi cisternae are concentrically arranged near the nucleus with distinct convex cis or the forming face and concave trans or the maturing face.
  • Materials to be packaged in the form of vesicles from the ER fuse with the cis face of the Golgi apparatus and move towards the maturing face, where packaging of materials take place.
  • Glycoproteins and glycolipids are synthesized in Golgi apparatus.
