This set of Microbiology Multiple Choice Questions & Answers (MCQs) focuses on “Fungi – Molds and Yeasts – Reproduction”.
1. Which among the following are asexual spores?
a) Blastospores
b) Ascospores
c) Basidiospores
d) Zygospores
View Answer
Explanation: Blastospores are asexual spores and are formed by budding.
2. Aplanospores are _____________
a) motile sporangiospores
b) nonmotile sporangiospores
c) oidia
d) chlamydospores
View Answer
Explanation: Aplanospores are nonmotile sporangiospores. Sporangiospores are single-celled spores and are formed within the sporangium.
3. Which among the following are spores formed by budding?
a) Arthrospores
b) Chlamydospores
c) Blastospores
d) Conidiospores
View Answer
Explanation: Blastospores are asexual spores and are formed by budding.
4. Spores formed by sexual reproduction on a club-shaped structure are _______________
a) Ascospores
b) Zygospores
c) Basidiospores
d) Oospores
View Answer
Explanation: Basidiospores are single-celled spores borne on a club-shaped structure called a basidium.
5. Asexual fruiting bodies have name such as ________________
a) perithecium
b) pycnidium
c) antheridium
d) apothecium
View Answer
Explanation: Fruiting bodies are highly organized protective structures that surround the asexual and sexual spores. Asexual fruiting bodies have names such as acervulus and pycnidium.
6. There are one or more oospheres in each oogonium.
a) True
b) False
View Answer
Explanation: Oospheres are eggs formed within a special female structure, the oogonium. There are one or more oospheres in each oogonium.
7. How many ascospores are present in each ascus?
a) Four
b) Six
c) Two
d) Eight
View Answer
Explanation: Ascospores are single-celled spores produced in a sac called an ascus. These are usually eight ascospores in each ascus.
8. Which of the following spores are formed at the tips of sterigmata?
a) Zygospores
b) Oospores
c) Basidiospores
d) Blastospores
View Answer
Explanation: Basidiospores are formed exogenously at the tips of the special outgrowths called sterigmata. Usually four spores are formed at the tip of each sterigma.
9. The process of fusion of nuceus of two mating types is known as plasmogamy.
a) True
b) False
View Answer
Explanation: The two haploid nuclei of two mating types fuse together to form a diploid nucleus and this process is known as karyogamy.
10. In which of the following process does the male nucleus migrates through a fertilization tube into the female gametangium?
a) Gametic copulation
b) Gamete-gametangial copulation
c) Gametangial copulation
d) Somatic copulation
View Answer
Explanation: In gamete-gametangial copulation, the two gametangia come into contact but do not fuse; the male nucleus migrates through a pore or fertilization tube into the female gametangium.
11. Which of the following spores are formed by the disjointing of hyphal cells?
a) Conidiospores
b) Chlamydospores
c) Oidia
d) Zoospores
View Answer
Explanation: Oidia or arthrospores are single-celled spores formed by disjointing of hyphal cells.
