Matching cell structure functions to appearances Steps:

• Identify function 1 (mRNA passes through ribosome) matches non-membrane-bound spherical structures (ribosomes, X).
• Identify function 2 (produces mitotic spindle) matches non-membrane-bound cylindrical structures (centrioles, Z).
• Identify function 3 (packages hydrolytic enzymes in cell) matches membrane-bound enclosed cavity (lysosomes, V).
• Compare to choices, but C is blank and A includes undefined W, making options ambiguous.

Why D is correct: Not enough information due to incomplete choices.

Why the others are wrong:

• A includes undefined W, invalid match.
• B (V X Y) mismatches function 2 (V and Y not centrioles) and 3 (X not lysosomes).
• C blank, no matches provided.

Final answer: Not enough information.
