What Primary Structures Package Cellular Secretions for Export from the Cell

Question

What primary structures package cellular secretions for export from the cell?  
A) Golgi bodies
B) Ribosomes
C) Mitochondria
D) Lysosomes
E) Endoplasmic reticula

Accepted Answer

Golgi bodies are responsible for packaging cellular secretions for export from the cell. They modify, sort, and package proteins and lipids into vesicles for transport outside of the cell. Ribosomes, mitochondria, lysosomes, and endoplasmic reticula are not primarily involved in packaging cellular secretions for export from the cell.
