In 1898 he identified what he termed the "internal reticular apparatus"; the identification of this structure, which would later be named the Golgi complex, was a major breakthrough in cytology.

The point of all this is that, although it is known which enzymes are active in a natural Golgi apparatus, the details of how the modifications happen are obscure.

The cell contains profusely rough endoplasm rete and Golgi apparatus. which show that the cell possess active metabolism function.
