1. Which organelle is the site of protein synthesis?
A. Mitochondria
B. Ribosome
C. Lysosome
D. Golgi apparatus
Correct Answer: B
Rationale: Ribosomes synthesize proteins either free in the
cytoplasm or attached to rough ER.
2. Which organelle modifies, sorts, and packages proteins?
A. Golgi apparatus
B. Ribosome
C. Smooth ER
D. Lysosome
Correct Answer: A
Rationale: Golgi apparatus processes proteins and directs them to
their destinations.
,3. Which organelle produces ATP?
A. Lysosome
B. Mitochondria
C. Ribosome
D. Smooth ER
Correct Answer: B
Rationale: Mitochondria generate cellular energy through
respiration.
4. Which solution causes a cell to swell?
A. Hypertonic
B. Hypotonic
