Golgi apparatus was discovered in the year 1898 by an Italian biologist Camillo Golgi. It was on of the first cellular organelles to be discovered and observed in detail due to its large size. The term Golgi apparatus was used in 1910 and in 1913 it first appeared in the scientific literature.

 

With the aids of special staining techniques the Golgi bodies were seen as densely stained region of the cytoplasm under the optical microscope. Under the electron microscope the Golgi apparatus is seen to be composed of stacks of flattened structures which contains numerous vesicles containing secretory granules. The newly synthesized proteins, found in the channels of the rough endoplasmic reticulum are moved to the Golgi body where the carbohydrates are added to them and these molecules are enveloped in a part of the Golgi membrane and then the enveloped molecules leave the cell. The Golgi apparatus hence acts as the assembly factory of the cell where the raw materials are directed to the Golgi apparatus before being passed out from the cell.
