Correct | Grade A - Chamberlain
1. Which phase of mitosis is characterized by chromosome
condensation?
A. Metaphase
B. Prophase
C. Anaphase
D. Telophase
Correct Answer: B
Rationale: Prophase is when chromosomes condense and spindle
fibers form.
2. Which organelle is responsible for ATP production?
A. Mitochondria
B. Ribosome
C. Lysosome
D. Golgi apparatus
Correct Answer: A
Rationale: Mitochondria generate ATP through cellular respiration.
3. Which macromolecule is composed of nucleotides?
A. Carbohydrate
B. Protein
,C. Nucleic acid
D. Lipid
Correct Answer: C
Rationale: DNA and RNA are polymers of nucleotides.
4. Which organelle digests cellular waste and old organelles?
A. Lysosome
B. Golgi apparatus
C. Ribosome
D. Smooth ER
Correct Answer: A
Rationale: Lysosomes contain digestive enzymes that break down
waste.
5. Which solution causes a cell to swell?
A. Hypertonic
B. Hypotonic
C. Isotonic
D. Acidic
Correct Answer: B
Rationale: Water moves into the cell in a hypotonic solution.
6. Which organelle synthesizes proteins for secretion?
A. Rough ER
B. Smooth ER
C. Lysosome
D. Golgi apparatus
Correct Answer: A
Rationale: Ribosomes on the rough ER produce proteins for export.
7. Facilitated diffusion requires:
, A. ATP
B. Transport proteins
C. Vesicles
D. Energy input
Correct Answer: B
Rationale: Transport proteins assist molecules in moving passively
across membranes.
8. Which organelle modifies and ships proteins?
A. Golgi apparatus
B. Ribosome
C. Lysosome
D. Smooth ER
Correct Answer: A
Rationale: Golgi apparatus packages proteins for delivery.
9. Which macromolecule provides long-term energy storage?
A. Carbohydrate
B. Protein
C. Lipid
D. Nucleic acid
Correct Answer: C
Rationale: Lipids store energy efficiently for long-term use.
10. Which organelle stores the cell’s genetic material?
A. Nucleus
B. Ribosome
C. Lysosome
D. Cytoplasm
Correct Answer: A
Rationale: DNA is stored in the nucleus, controlling cell activities.
11. Which macromolecule forms enzymes?
