Matching Cell Functions to Structures

Steps:

• Function 1 (polypeptide synthesis) matches ribosomes, non-membrane-bound structures (W).
• Function 2 (lipid synthesis) matches smooth endoplasmic reticulum, membrane networks enclosing cavities (V).
• Function 3 (packaging hydrolytic enzymes for cell retention) matches Golgi apparatus, stacked membrane-bound sacs (Z).
• Verify option A aligns all three correctly.

Why A is correct:

• It pairs each function with the defining structure: ribosomes (free or rough ER-associated) for proteins, smooth ER for lipids, and Golgi for enzyme packaging into lysosomes per cell biology definitions.

Why the others are wrong:

• B: Assigns polypeptides to Golgi (Z, wrong; Golgi modifies, doesn't synthesize) and lipids to unknown W.
• C: Assigns polypeptides to ribosomes (W, correct) but lipids to Golgi (Z, wrong) and enzymes to membranes (V, wrong).
• D: Assigns polypeptides to Golgi (Z, wrong) and enzymes to unknown W.

Final answer: A
