1. Which organelle is responsible for energy (ATP) production in
cells?
A. Nucleus
B. Mitochondria
C. Ribosome
D. Golgi apparatus
Correct Answer: B
Rationale:Mitochondria generate ATP through cellular respiration,
supplying energy for cellular functions.
2. What is the primary function of ribosomes?
A. Protein synthesis
B. Lipid metabolism
C. DNA replication
D. Energy production
Correct Answer: A
,Rationale:Ribosomes translate mRNA into polypeptides, producing
proteins needed by the cell.
3. Which organelle modifies, sorts, and packages proteins for
secretion?
A. Lysosome
B. Golgi apparatus
C. Endoplasmic reticulum
D. Nucleus
Correct Answer: B
Rationale:Golgi apparatus receives proteins from the ER, modifies
them, and directs them to their destinations.
4. Which organelle is involved in detoxification of drugs and
chemicals?
A. Smooth ER
B. Rough ER
C. Lysosome
D. Ribosome
Correct Answer: A
Rationale:Smooth ER metabolizes toxins and synthesizes lipids,
unlike rough ER which has ribosomes.
5. Which cell structure controls what enters and exits the cell?
,A. Cytoplasm
B. Cell membrane
C. Nucleus
D. Mitochondria
Correct Answer: B
Rationale:The plasma membrane regulates transport of substances
in and out of the cell.
6. Which organelle contains digestive enzymes to break down
waste?
A. Peroxisome
B. Lysosome
C. Mitochondria
D. Ribosome
Correct Answer: B
Rationale:Lysosomes digest cellular waste, old organelles, and
foreign materials.
7. Which organelle contains DNA and controls cell activities?
A. Nucleus
B. Mitochondria
C. Ribosome
D. Golgi apparatus
Correct Answer: A
, Rationale:The nucleus stores genetic material and regulates gene
expression and cell function.
8. Which cytoskeletal component is responsible for cell shape and
movement?
A. Microfilaments
B. Microtubules
C. Intermediate filaments
D. Ribosomes
Correct Answer: A
Rationale:Microfilaments, composed of actin, provide structural
support and aid in movement.
9. Which cytoskeletal structure forms cilia and flagella?
A. Microfilaments
B. Microtubules
C. Intermediate filaments
D. Ribosomes
Correct Answer: B
Rationale:Microtubules make up the core of cilia and flagella,
enabling motility.
10. Which organelle produces hydrogen peroxide to detoxify
harmful molecules?
