Answer: (A) Agaricus. Answer: (A) Agaricus Solution: Agaricus is a basidiomycete in which karyogamy and meiosis occur in the basidium, producing four basidiospores that are borne exogenously on the basidium.
- A.Agaricus✓
- B.Alternaria
- C.Neurospora
- D.Saccharomyces
Correct Answer
(A) Agaricus
Solution & Explanation
Answer: (A) Agaricus Solution: Agaricus is a basidiomycete in which karyogamy and meiosis occur in the basidium, producing four basidiospores that are borne exogenously on the basidium. Alternaria is a deuteromycete (asexual conidia), Neurospora an ascomycete (endogenous ascospores), and Saccharomyces an ascomycete; only Agaricus forms spores exogenously after karyogamy and meiosis.
