Actual Exam Questions, Verified Answers & Detailed
Rationales
1. Which level of structural organization is considered to be the highest
level?
A) Organ
B) Tissue
C) Organismal
D) Cellular
Answer: C) Organismal
Rationale: The organismal level represents the highest level of structural
organization, as it encompasses all other levels working together to form
a complete living being.
2. Histology would be best defined as a study of ________.
A) Cells
B) Tissues
C) Organs
D) Organ systems
Answer: B) Tissues
Rationale: Histology is the microscopic study of tissues, which are
groups of similar cells that perform a common function.
3. The nucleolus is the cellular site of:
A) ATP production
B) Protein synthesis
C) Ribosome assembly
D) Lipid synthesis
,2|Page
Answer: C) Ribosome assembly
Rationale: The nucleolus is a dense region within the nucleus
responsible for the assembly of ribosomal subunits, which are essential
for protein synthesis.
4. Which cell organelle provides the majority of the ATP needed by the
cell to carry out its metabolic reactions?
A) Nucleus
B) Ribosome
C) Golgi apparatus
D) Mitochondrion
Answer: D) Mitochondrion
Rationale: Mitochondria are the powerhouses of the cell, generating the
majority of ATP through aerobic cellular respiration to fuel metabolic
activities.
5. Which cell component helps to maintain the structural integrity of the
cell?
A) Cytoskeleton
B) Nucleus
C) Smooth ER
D) Lysosome
Answer: A) Cytoskeleton
Rationale: The cytoskeleton is a network of protein filaments that
provides structural support, maintains cell shape, and facilitates
intracellular transport.
6. The functions of centrioles include ________.
A) Organizing the mitotic spindle in cell division
B) Synthesizing proteins
C) Producing ATP
D) Packaging cellular products
Answer: A) Organizing the mitotic spindle in cell division
Rationale: Centrioles are microtubule-organizing centers that play a
,3|Page
crucial role in forming the mitotic spindle, which separates
chromosomes during cell division.
7. Microtubules are hollow tubes made of subunits of the protein tubulin.
A) True
B) False
Answer: A) True
Rationale: Microtubules are indeed hollow, cylindrical structures
composed of dimers of the protein tubulin, serving as major components
of the cytoskeleton.
8. Which of the following is incorrectly matched?
A) Simple squamous epithelia: found in the air sacs of the lungs
B) Simple cuboidal epithelia: found in areas that stretch
C) Stratified squamous epithelia: found in the skin
D) Pseudostratified columnar epithelia: found lining the trachea
Answer: B) Simple cuboidal epithelia: found in areas that stretch
Rationale: Simple cuboidal epithelia are not found in areas that stretch;
that is a characteristic of transitional epithelium. Simple cuboidal
epithelium is typically found in glands and kidney tubules.
9. Where is transitional epithelium found?
A) In areas subjected to stretching
B) Lining the trachea
C) In the air sacs of the lungs
D) In the lining of the stomach
Answer: A) In areas subjected to stretching
Rationale: Transitional epithelium is specialized to stretch and is found
in organs like the urinary bladder, ureters, and urethra, which undergo
significant distension.
10. Which of the following describes a holocrine gland?
A) Holocrine glands secrete their products by rupturing.
B) Holocrine glands secrete their products via exocytosis.
C) Holocrine glands secrete their products into the blood.
, 4|Page
D) Holocrine glands release their products by shedding the apical
portion of the cell.
Answer: A) Holocrine glands secrete their products by rupturing.
Rationale: Holocrine glands accumulate their secretory product within
the cell and then release it by the complete rupture of the cell, destroying
it in the process.
11. _______________ is a water-soluble, complex glycoprotein that is
secreted by all unicellular exocrine glands.
A) Serous fluid
B) Mucin
C) Hormones
D) Enzymes
Answer: B) Mucin
Rationale: Mucin is a complex glycoprotein that, when mixed with water,
forms mucus. It is a key secretion of unicellular exocrine glands like
goblet cells.
12. In connective tissue, the role of collagen fibers is to:
A) Provide tensile strength
B) Provide elasticity
C) Provide a flexible framework
D) Store energy
Answer: A) Provide tensile strength
Rationale: Collagen fibers are strong and flexible, providing significant
tensile strength to connective tissues, resisting pulling forces.
13. Which type of gland produces hormones?
A) Exocrine glands
B) Endocrine glands
C) Holocrine glands
D) Apocrine glands
Answer: B) Endocrine glands
