Matching Cell Organelles to Their Functions

Steps:

• Recall functions: ribosomes synthesize proteins; rough ER modifies proteins with ribosomes attached; smooth ER synthesizes lipids and detoxifies; Golgi body packages and modifies proteins/lipids.
• Examine choice A: assigns Golgi to W (packaging), ribosome to X (synthesis), rough ER to Z (modification), smooth ER to Y (lipid synthesis).
• Verify alignment with standard biology definitions for each structure.
• Confirm no other choice matches all functions correctly.

Why A is correct:

• It accurately pairs each organelle with its primary function per cell biology: ribosomes for protein synthesis (X), rough ER for protein processing (Z), smooth ER for lipid metabolism (Y), Golgi for secretion (W).

Why the others are wrong:

• B: Mismatches ribosome to Z (not synthesis) and rough ER to X (not modification).
• C: Assigns Golgi to Z (not packaging) and ribosome to Y (not synthesis).
• D: Incomplete option provides no valid matches.
