1. Which tissue type forms the lining of the digestive tract?
A. Simple columnar
B. Stratified squamous
C. Pseudostratified columnar
D. Transitional
Correct Answer: A
Rationale: Simple columnar epithelium allows absorption and
secretion in the digestive tract.
2. Which connective tissue cushions organs and stores energy?
A. Adipose
B. Dense irregular
C. Reticular
D. Areolar
Correct Answer: A
Rationale: Adipose stores triglycerides and provides insulation and
cushioning.
3. Which connective tissue resists tension in multiple directions?
,A. Dense irregular
B. Dense regular
C. Areolar
D. Elastic cartilage
Correct Answer: A
Rationale: Collagen fibers arranged irregularly allow
multidirectional strength.
4. Which cartilage is found in the intervertebral discs?
A. Fibrocartilage
B. Hyaline
C. Elastic cartilage
D. Bone
Correct Answer: A
Rationale: Fibrocartilage absorbs compression between vertebrae.
5. Which cartilage provides flexible support in the external ear?
A. Elastic cartilage
B. Fibrocartilage
C. Hyaline
D. Bone
Correct Answer: A
Rationale: Elastic cartilage maintains shape while being flexible.
6. Which epithelium lines alveoli for gas exchange?
,A. Simple squamous
B. Simple cuboidal
C. Stratified squamous
D. Transitional
Correct Answer: A
Rationale: Thin squamous cells allow diffusion of gases.
7. Which epithelium has cilia and lines the trachea?
A. Pseudostratified columnar
B. Stratified squamous
C. Simple cuboidal
D. Transitional
Correct Answer: A
Rationale: Ciliated pseudostratified columnar epithelium moves
mucus.
8. Which organelle synthesizes proteins?
A. Ribosome
B. Smooth ER
C. Lysosome
D. Golgi apparatus

9. Which organelle packages and modifies proteins?
, A. Golgi apparatus
B. Ribosome
C. Lysosome
D. Smooth ER
Correct Answer: A
Rationale: Golgi modifies proteins for secretion or transport.
10. Which organelle produces ATP?
A. Mitochondria
B. Golgi apparatus
C. Lysosome
D. Ribosome
Correct Answer: A
Rationale: Mitochondria generate energy via cellular respiration.
11. Which organelle synthesizes lipids and detoxifies chemicals?
A. Smooth ER
B. Rough ER
C. Golgi
D. Lysosome
Correct Answer: A
Rationale: Smooth ER produces lipids and metabolizes toxins.
12. Which phase of mitosis aligns chromosomes at the metaphase
plate?
