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: DNA is replicated during the S phase to prepare for
mitosis.
2. Which phase of the cell cycle prepares the cell for mitosis?
A. G1 phase
B. S phase
C. G2 phase
D. M phase
Correct Answer: C
Rationale: G2 phase allows the cell to synthesize proteins and
organelles needed for mitosis.
,3. Which phase of the cell cycle involves cell division?
A. G1 phase
B. S phase
C. G2 phase
D. M phase
Correct Answer: D
Rationale: M phase is when mitosis and cytokinesis occur.
4. During which phase do chromosomes condense?
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase
Correct Answer: A
Rationale: Chromosomes condense in prophase to prepare for
alignment.
5. During which phase do chromosomes align at the cell equator?
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase
Correct Answer: B
Rationale: Chromosomes align at the metaphase plate during
metaphase.
,6. During which phase do sister chromatids separate?
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase
Correct Answer: C
Rationale: Anaphase pulls sister chromatids apart toward opposite
poles.
7. During which phase do nuclear envelopes reform?
A. Prophase
B. Metaphase
C. Anaphase
D. Telophase
Correct Answer: D
Rationale: Nuclear envelopes reform during telophase.
8. Which organelle is involved in protein synthesis?
A. Nucleus
B. Ribosome
C. Lysosome
D. Mitochondria
Correct Answer: B
Rationale: Ribosomes translate mRNA into polypeptides.
, 9. Which organelle modifies and packages proteins?
A. Golgi apparatus
B. Rough ER
C. Lysosome
D. Smooth ER
Correct Answer: A
Rationale: Golgi apparatus processes and packages proteins for
secretion or cellular use.
10. Which organelle produces ATP?
A. Chloroplast
B. Mitochondria
C. Lysosome
D. Ribosome
Correct Answer: B
Rationale: Mitochondria generate energy via cellular respiration.
11. Which organelle performs photosynthesis?
A. Chloroplast
B. Mitochondria
C. Lysosome
D. Ribosome
Correct Answer: A
Rationale: Chloroplasts convert light energy into chemical energy.
