Golgi Apparatus

Golgi apparatus was discovered by Golgi in 1898. This apparatus, which was found virtually in all
eukaryotic cells, consists of stacks of flattened, membrane bound sacs, called cisternae. These
cisternae together with associated vesicles are called Golgi complex. It is a complex system of
interconnected tubules around the central stacks. Cisternae stacks are continuously formed by
fusion of vesicles, which are probably derived by the budding of SER. Their outer convex surface is
the forming face, while the inner concave surface is the maturing face. The cisternae break up into
vesicles from the latter. The whole stack consists of a number of cisternae thought to be moving
from the outer to the inner face.
