Free Kingdom Fungi MCQs with Answers

231. In general, asexual reproduction is common in:

• A. Humans
• B. Basidiomycota
• C. Deuteromycota
• D. Basidiospores

Explanation: Deuteromycota commonly reproduce via asexual reproduction throught the conidia; a sexual phase has not yet been observed. Basidiomycota mainly sexually reproduce through basidiospores; asexual reproduction is uncommon. Humans cannot reproduce asexually.

232. Name the nutrition resulted by feeding on dead and decaying matter.

• A. Saprophytic.
• B. Symbiotic.
• C. Parasitic.
• D. Both B and C.

Explanation: Saprophytes are living organisms that live and feed on the remains of other organisms i.e on dead and decaying organisms.

233. Penicillin is obtained from:

• A. Penicillium notatum
• B. Aspergillus fumigatus
• C. Aspergillus flavus
• D. Penicillium chrysogenum

Explanation: Penicillium notatum is the fungus from which Alexander Fleming first isolated penicillin in 1928, marking a groundbreaking advancement in the treatment of bacterial infections. While Penicillium chrysogenum is used in industrial production today due to its higher yield of penicillin, Penicillium notatum remains historically important for its initial role in antibiotic discovery. Aspergillus fumigatus and Aspergillus flavus are unrelated to penicillin production, with the former being a pathogen and the latter a producer of harmful toxins.

234. Which one of the following fungi causes vaginal thrush?

• A. Candida
• B. Aspergillus
• C. Tortula
• D. Penicillium

Explanation: Option [A] Most thrush is caused by Candida albicans.

235. _ is the yeast that grows in the mucous membrane of the mouth or vagina.

• A. Candida albicans
• B. Saccharomyces cerevisiae
• C. Aspergillus fumigatus
• D. Aspergillus flavus

Explanation: Candida albicans, an opportunistic pathogenic yeast is a common member of the human mouth and vaginal flora.

236. Chitin, a chemical found in exoskeleton of arthropods is also found in cell wall of:

• A. Bacteria
• B. Fungi
• C. Cyanobacteria
• D. Algae

Explanation: Chitin is a substance made from fibrous polysaccharides. They are famously known for being used to construct the cell walls of eukaryotic Fungi.

237. Cup_like ascocarp in fungi is:

• A. Apothecium
• B. Perithecium
• C. Hysterothylacium
• D. Cleistothecium

Explanation: The correct answer is Apothecium. An apothecium is a cup-shaped ascocarp with an exposed hymenium. This structure fits the description of a cup-like ascocarp in fungi, making it the correct choice. Perithecium, Hysterothylacium, and Cleistothecium are all different types of ascocarps, but they do not match the specific cup-like morphology mentioned in the question.

238. Early blight of potato is caused by:

• A. Alternaria_solani
• B. Phytophthora_infestans
• C. Erysiphe_graminls
• D. Claviceps_purpurea

Explanation: Alternaria solani is the correct answer as it is the fungal pathogen responsible for early blight of potato, causing specific symptoms on potato plants. The other options, such as Phytophthora infestans, Erysiphe graminis, and Claviceps purpurea, are pathogens that affect different plants and do not cause early blight in potatoes.

239. Microsporum furfur causes:

• A. Athletes foot
• B. Ringworm
• C. Dandruff
• D. Ergot

Explanation: Microsporum furfur is a type of fungus that is associated with the condition known as dandruff. Dandruff is a common scalp disorder characterized by the shedding of dead skin cells from the scalp, resulting in visible flakes.

240. An organism that adopts saprophytic mode of nutrition during part of its life is called:

• A. Facultative saprophyte
• B. Facultative parasite
• C. Obligate saprophyte
• D. Obligate parasite

Explanation: Saprophytic is the mode of nutrition in which organisms feed on dead and decayed matter, a facultative saprophyte ia a mainly parasitic organism with the ability to survive for a part of its life cycle as a saprophyte, therefore the answer will be A.
