Here's how it works:

* Modification: The Golgi apparatus receives proteins and lipids (fats) from the endoplasmic reticulum (ER). It modifies these molecules, adding sugars or other chemical groups, to ensure they are properly folded and functional.

* Packaging: The modified molecules are then packaged into small membrane-bound sacs called vesicles.

* Distribution: These vesicles can then be transported to different destinations within the cell, or they can fuse with the cell membrane and release their contents outside the cell.

So, the Golgi apparatus is a key player in the cell's protein and lipid processing and distribution system.
