Cells as the basic units of living organisms — practice question

Four students had to link each function to the form of certain cell structures in an animal cell. The functions were given as numbers: 1 synthesis of polypeptides, 2 synthesis of lipids, 3 packaging of hydrolytic enzymes that will remain in the cell. The forms were given as letters: V membranes that enclose a central cavity, W spherical structures with no membrane, X a double membrane with pores between it, Y cylindrical structures with no membrane, Z membrane-bound sacs arranged in a flattened stack. Which student made the correct match between the numbered function and the form of the cell structure?
