Here's a breakdown:

* Golgi apparatus: A stack of flattened, membrane-bound sacs (cisternae) that modifies, sorts, and packages proteins and lipids made in the endoplasmic reticulum (ER).

* Function:

* Modification: The Golgi adds sugars and other molecules to proteins and lipids.

* Sorting: The Golgi directs proteins and lipids to their final destinations, either within the cell or outside of it.

* Packaging: The Golgi packages substances into vesicles, small membrane-bound sacs that transport them to different parts of the cell or to the cell exterior.
