Here's how it works:
1. Proteins and lipids are synthesized in the endoplasmic reticulum (ER).
2. These molecules are packaged into transport vesicles that bud off from the ER.
3. These vesicles move to the Golgi apparatus, a stack of flattened membrane-bound sacs.
4. As the vesicles move through the Golgi, their contents are modified, sorted, and packaged into new vesicles.
5. Secretory vesicles, containing molecules destined for export, bud off from the Golgi.
6. These vesicles move to the cell membrane and fuse with it, releasing their contents outside the cell.
So, in short, Golgi bodies utilize transport vesicles as their "delivery trucks" to move molecules from the ER to their final destination, either within the cell or outside of it.
