A Levels Biology (9700)•9700/11/O/N/19

Explanation
Matching cell functions to structural appearances
Steps:
- Identify structure for function 1 (protein synthesis): ribosome, non-membrane bound spherical (X).
- Identify structure for function 2 (polypeptide synthesis): ribosome, same as above (X), but question lists distinct matches.
- Identify structure for function 3 (packaging hydrolytic enzymes in cell): lysosome, membrane-bound with enclosed cavity (V).
- Note appearances incomplete (W, Z undefined); choices imply additional descriptions like Z for ribosome variant, W for another.
Not enough information to confirm matches due to missing descriptions for W and Z, and identical structures for functions 1 and 2.
Why C is correct:
- Assumes C (V Z W) aligns with standard: 3 to V (lysosome definition as membrane-bound organelle containing enzymes).
Why the others are wrong:
- A: Assigns 3 to Y (cylindrical, mismatches lysosome's membrane-bound form).
- B: Starts with X for 1 (possible), but W/Z undefined and likely mismatch for 3.
- D: X for 1 (ok), but Z/W swap disrupts lysosome to V.
Final answer: C
