1. Which phase of the cell cycle involves DNA replication?
A. G1 phase
B. S phase
C. G2 phase
D. M phase
Correct Answer: B
Rationale: During S phase, DNA is replicated in preparation for cell
division.
2. Which organelle is responsible for protein synthesis?
A. Ribosome
B. Golgi apparatus
C. Lysosome
D. Nucleus
Correct Answer: A
Rationale: Ribosomes link amino acids to form proteins.
,3. Which organelle is responsible for modifying and packaging
proteins?
A. Ribosome
B. Golgi apparatus
C. Lysosome
D. Smooth ER
Correct Answer: B
Rationale: The Golgi apparatus processes and ships proteins to their
destinations.
4. What is the primary function of mitochondria?
A. Protein synthesis
B. ATP production
C. Lipid synthesis
D. Waste digestion
Correct Answer: B
Rationale: Mitochondria convert glucose into ATP for cellular
energy.
5. Which solution causes water to enter a cell, making it swell?
A. Hypertonic
B. Hypotonic
C. Isotonic
D. Neutral
,Correct Answer: B
Rationale: Water moves into the cell in hypotonic solutions.
6. Which macromolecule stores genetic information?
A. Protein
B. Nucleic acid
C. Lipid
D. Carbohydrate
Correct Answer: B
Rationale: DNA and RNA carry and transmit genetic information.
7. Active transport differs from passive transport because it:
A. Moves molecules down their gradient
B. Requires ATP
C. Occurs spontaneously
D. Moves water only
Correct Answer: B
Rationale: Active transport requires energy to move molecules
against the concentration gradient.

synthesizing lipids?
A. Rough ER
B. Smooth ER
, C. Lysosome
D. Golgi
Correct Answer: B
Rationale: Smooth ER produces lipids and metabolizes toxins.
