Question

̌Which is of the following statements is incorrect about fungi?

• A. Morels and truffles are delicacies that can be eaten.
• B. Many alkaloids including LSD can be found in Claviceps.
• C. Conidia and ascospores are formed exogenously and endogenously, respectively.
• D. Yeasts have filamentous bodies with long hyphae that look like threads.

Answer 1

The correct option is D

Yeasts have filamentous bodies with long hyphae that look like threads.

The correct option is D.

Explanation for the correct option:

1. Yeasts are members of the kingdom fungi.
2. Fungi are eukaryotic organisms that are non-vascular, non-motile, and heterotrophic.
3. Fungi are filamentous, with the exception of yeasts, which are unicellular.
4. Yeasts are unicellular fungi.

Explanation for the incorrect option.:

Option A:

1. Morels are similar to mushrooms in that they have a cap on a central stem, whereas truffles are solid, round balls that grow underground.
2. Fungi like morels and truffles are edible and considered a delicacy. They belong under the Ascomycetes class of the kingdom of fungi.
3. Morels and truffles are two of the most sought-after edible mushrooms on the planet.

Option B:

1. The clavinet, lysergic acids, lysergic acid amides, and oligopeptides are the four main classes of ergot alkaloids.
2. Claviceps contain a wide variety of fungus species that generate ergot alkaloids.
3. This fungus thrives on rye and similar plants, and it generates alkaloids that, when consumed by mammals and humans, can lead to ergotism.

Option C:

1. Ascospores and conidia are two types of spores found in the life cycle of a fungus
2. Ascospores are sexual spores that are produced endogenously in sac-like asci.
3. Conidia are asexual spores produced exogenously on the special mycelium called conidiophores.

Final Answer: Yeasts have filamentous bodies with long hyphae that look like threads are incorrect about fungi.
