Question

Which of the following statements is incorrect?

Accepted Answer

Correct Answer: A — Yeasts have filamentous bodies with long thread-like hyphae.Statement A is incorrect. Yeasts are unicellular fungi; they do not have filamentous bodies or hyphae. They exist as single oval or spherical cells and reproduce asexually by budding (e.g., Saccharomyces cerevisiae) or fission. It is the molds (e.g., Rhizopus, Penicillium, Aspergillus) that are filamentous and possess thread-like structures called hyphae (collectively forming a mycelium).Why other options are correct:Option B is correct: Morels (Morchella) and truffles (Tuber) are ascomycete fungi prized as edible delicacies in cooking worldwide. Option C is correct: Claviceps purpurea, the ergot fungus (ascomycete), parasitizes rye and other cereals and produces ergot alkaloids including lysergic acid, which is the precursor of LSD (lysergic acid diethylamide). Option D is correct: In Ascomycetes, conidia (asexual spores) are produced exogenously (externally on conidiophores), whereas ascospores (sexual spores) are produced endogenously within a sac-like structure called the ascus.Key Concept: Yeasts = unicellular fungi (no hyphae, no filamentous body); reproduce by budding. Molds = filamentous fungi with hyphae. Conidia = exogenous; ascospores = endogenous (inside ascus).
