1. Mycology is the study of:
A. Bacteria
B. Viruses
C. Fungi
D. Parasites
Correct Answer: C. Fungi
Rationale: Mycology is the branch of microbiology that studies fungi, including
their biology, classification, and diseases.
2. Fungi are classified as:
A. Prokaryotes
B. Viruses
C. Eukaryotes
D. Archaea
Correct Answer: C. Eukaryotes
Rationale: Fungi contain membrane-bound organelles and a true nucleus, making
them eukaryotic organisms.
3. The fungal cell wall is primarily composed of:
,A. Cellulose
B. Peptidoglycan
C. Chitin
D. Lipopolysaccharide
Correct Answer: C. Chitin
Rationale: Chitin is a major structural component of fungal cell walls.
4. The main sterol found in fungal cell membranes is:
A. Cholesterol
B. Ergosterol
C. Testosterone
D. Cortisol
Correct Answer: B. Ergosterol
Rationale: Ergosterol maintains fungal membrane integrity and is a target of
several antifungal drugs.
5. A unicellular fungus is called a:
A. Mold
B. Hypha
C. Yeast
D. Mycelium
Correct Answer: C. Yeast
Rationale: Yeasts are single-celled fungi that commonly reproduce by budding.
6. A multicellular filamentous fungus is called a:
A. Yeast
B. Virus
,C. Mold
D. Protozoan
Correct Answer: C. Mold
Rationale: Molds consist of filamentous structures called hyphae.
7. The thread-like structures of molds are called:
A. Spores
B. Capsules
C. Hyphae
D. Buds
Correct Answer: C. Hyphae
Rationale: Hyphae are branching filaments that form the body of filamentous
fungi.
8. A mass of hyphae is called a:
A. Spore
B. Mycelium
C. Capsule
D. Conidium
Correct Answer: B. Mycelium
Rationale: A mycelium is the network of interconnected fungal hyphae.
9. Fungi reproduce asexually by producing:
A. Ribosomes
B. Spores
C. Peptidoglycan
D. Flagella
Correct Answer: B. Spores
, Rationale: Many fungi reproduce asexually through specialized spores.
10. The most common method of yeast reproduction is:
A. Binary fission
B. Fragmentation
C. Budding
D. Conjugation
Correct Answer: C. Budding
Rationale: Most yeasts reproduce by forming a smaller daughter cell from the
parent cell.
11. Dimorphic fungi exist in:
A. Two bacterial forms
B. Two fungal forms depending on conditions
C. Only yeast form
D. Only mold form
Correct Answer: B. Two fungal forms depending on conditions
Rationale: Dimorphic fungi can switch between yeast and mold forms depending
on temperature or environment.
12. The yeast form of a dimorphic fungus is usually associated with:
A. Environmental growth only
B. Growth in host tissues
C. Spore production only
D. Soil reproduction only
Correct Answer: B. Growth in host tissues
Rationale: Many pathogenic dimorphic fungi grow as yeast in the human body.
