What is the difference between Rough ER and Smooth ER? A: Rough ER has ribosomes and makes proteins; Smooth ER makes lipids and detoxifies.

Why is the Golgi apparatus compared to a "post office"? A: It modifies, sorts, and packages proteins into vesicles for delivery inside or outside the cell. Section 7-2 Eukaryotic Cell Structure Answer Key Fixed
