Matching cell structures to functions by description

Steps:

• Identify function 1 (polypeptide synthesis) with ribosomes: non-membrane-bound, spherical structures (W).
• Identify function 2 (lipid synthesis) with smooth ER: membranes surrounding enclosed inner cavity (V).
• Identify function 3 (packaging hydrolytic enzymes in cell) with lysosomes: membrane-bound vesicles (assuming Z denotes this based on correct option A).
• Compare student matches to these standard assignments.

Why A is correct:

• A assigns W to 1 (ribosomes), V to 2 (smooth ER), and Z to 3 (lysosomes), aligning with organelle structures and functions in cell biology.

Why the others are wrong:

• B mismatches by assigning Z to 1 and 3, confusing ribosomes and lysosomes.
• C is incomplete, lacking a third match for function 3.
• D incorrectly swaps assignments, pairing Z with 1 (not ribosomes) and W with 3 (not lysosomes).

Final answer: A
