Question

Which pair has the correct combination?
A. Aspergillus - meiosis occurs in asci - produces citric acid
B. Albugo - coenocytic hyphae - parasite on mustard
C. Penicillium - basidiospores - multicellular
D. Colletotrichum - conidia - smut disease

• A. B, C
• B. C, D
• C. A, D
• D. A, B

Answer 1

The correct option is D A, B

Citric acid (vinegar) is obtained from Aspergillus niger. Meiosis occurs in asci (sac like spores containing structure) after the formation of the diploid zygote during sexual reproduction.

Albugo is an obligate parasite which attacks mostly crucifers like turnip, mustard, etc. An aseptate (no septum) hyphae called coenocytic (multinucleate) can be seen in Albugo.

Penicillium belongs to ascomycetes and it produces ascospores.

Smut disease is caused by Ustilago, not by Colleotrichum. Colleotrichum is an endophyte and a phytopathogen.
