The Golgi apparatus modifies proteins chemically and then repackages them.

The Golgi apparatus has been described as the shipping department for the cell's products. The Golgi apparatus receives newly produced proteins from the endoplasmic reticulum and changes them chemically. It then sorts and packages these proteins and readies them for transport outside of the cell or another location in the cell. The Golgi apparatus looks like a series of membranes that form a ribbon-like structure. The Golgi apparatus and the endoplasmic reticulum are part of the endomembrane system which also includes vacuoles, lysosomes, the nuclear envelope, and the plasma membrane.
