1. Medical mycology is the study of:
A. Viruses causing disease
B. Bacteria causing disease
C. Fungi that cause human disease
D. Parasites causing disease
Answer: C. Fungi that cause human disease
Rationale: Medical mycology focuses on fungal organisms that infect humans and
cause disease.
2. Fungi are classified as:
A. Prokaryotes
B. Viruses
C. Eukaryotes
D. Acellular organisms
Answer: C. Eukaryotes
Rationale: Fungi contain membrane-bound organelles and a true nucleus.
3. The main structural component of the fungal cell wall is:
A. Peptidoglycan
B. Cellulose
,C. Chitin
D. Lipopolysaccharide
Answer: C. Chitin
Rationale: Chitin is a polysaccharide that provides strength to fungal cell walls.
4. The fungal cell membrane contains:
A. Cholesterol only
B. Ergosterol
C. Peptidoglycan
D. Mycolic acid
Answer: B. Ergosterol
Rationale: Ergosterol is a major component of fungal membranes and a target of
many antifungal drugs.
5. A unicellular fungus is called a:
A. Mold
B. Yeast
C. Hypha
D. Mycelium
Answer: B. Yeast
Rationale: Yeasts are single-celled fungi that commonly reproduce by budding.
6. Multicellular filamentous fungi are called:
A. Yeasts
B. Protozoa
C. Molds
D. Viruses
Answer: C. Molds
,Rationale: Molds consist of filamentous structures called hyphae.
7. The filamentous structures of molds are called:
A. Spores
B. Capsules
C. Hyphae
D. Buds
Answer: C. Hyphae
Rationale: Hyphae are branching fungal filaments that form the body of molds.
8. A mass of hyphae is called:
A. Conidium
B. Mycelium
C. Blastospore
D. Capsule
Answer: B. Mycelium
Rationale: A mycelium is a network of interconnected hyphae.
9. Septate hyphae contain:
A. No nuclei
B. Cross walls separating segments
C. Viral particles
D. Bacterial cells
Answer: B. Cross walls separating segments
Rationale: Septa divide fungal hyphae into compartments.
10. Nonseptate hyphae are also called:
, A. Budding hyphae
B. Coenocytic hyphae
C. Septal hyphae
D. Capsule hyphae
Answer: B. Coenocytic hyphae
Rationale: Coenocytic hyphae lack internal septa and contain multiple nuclei.
11. A fungus that exists as yeast at one temperature and mold at another is:
A. A dermatophyte
B. A dimorphic fungus
C. A protozoan
D. A bacterium
Answer: B. A dimorphic fungus
Rationale: Dimorphic fungi can change form depending on environmental
conditions.
12. The phrase "mold at 25°C, yeast at 37°C" describes:
A. Viral replication
B. Thermal dimorphism
C. Bacterial transformation
D. Protozoal development
Answer: B. Thermal dimorphism
Rationale: Many pathogenic dimorphic fungi change form with temperature.
13. Fungal spores are mainly involved in:
A. Protein synthesis
B. Reproduction and dissemination
