Grade A - Chamberlain
1. What is the basic structural and functional unit of life?
A. Tissue
B. Organ
C. Cell
D. Organ system
Correct Answer: C. Cell
Rationale: Cells are the smallest units capable of independent life
and perform all vital functions.
2. Which organelle is responsible for energy production via ATP?
A. Nucleus
B. Mitochondria
C. Golgi apparatus
D. Lysosome
,Correct Answer: B. Mitochondria
Rationale: Mitochondria produce ATP through cellular respiration.
3. Which tissue type covers body surfaces and lines cavities?
A. Muscle
B. Nervous
C. Epithelial
D. Connective
Correct Answer: C. Epithelial
Rationale: Epithelial tissue protects, absorbs, secretes, and filters
substances.
4. Which connective tissue stores fat?
A. Cartilage
B. Bone
C. Adipose tissue
D. Blood
Correct Answer: C. Adipose tissue
Rationale: Adipose tissue stores energy in the form of lipids and
provides insulation.
5. Which type of muscle tissue is involuntary and non-striated?
A. Skeletal
B. Cardiac
C. Smooth
,D. All muscles
Correct Answer: C. Smooth
Rationale: Smooth muscle lines organs and is controlled
unconsciously.
6. Which type of muscle tissue is striated and voluntary?
A. Skeletal
B. Cardiac
C. Smooth
D. None
Correct Answer: A. Skeletal
Rationale: Skeletal muscles attach to bones and are under
conscious control.
7. Which type of muscle tissue is striated and involuntary?
A. Skeletal
B. Cardiac
C. Smooth
D. All muscles
Correct Answer: B. Cardiac
Rationale: Cardiac muscle contracts automatically to pump blood.
8. Which type of epithelial tissue is adapted for diffusion and
filtration?
, A. Simple squamous
B. Simple cuboidal
C. Simple columnar
D. Stratified squamous
Correct Answer: A. Simple squamous
Rationale: Thin, flat cells allow rapid exchange of gases and fluids.
9. Which epithelial tissue is found in the kidney tubules and
glands?
A. Simple squamous
B. Simple cuboidal
C. Simple columnar
D. Stratified squamous
Correct Answer: B. Simple cuboidal
Rationale: Cube-shaped cells facilitate secretion and absorption.
10. Which epithelial tissue lines the digestive tract and has
microvilli?
A. Simple squamous
B. Simple cuboidal
C. Simple columnar
D. Pseudostratified columnar
Correct Answer: C. Simple columnar
Rationale: Columnar cells increase surface area for absorption and
may contain goblet cells for mucus.
