Question

Choose the wrong statement.
A. Morels and truffles are poisonous mushrooms.
B. Yeast is unicellular and useful in fermentation.
C. Penicillium is multicellular and produces antibiotics.
D. Neurospora is used in the study of biochemical genetics.

Answer 1

Hint: Mushroom is a type of fungus that is grown on the soil or their food. It belongs to the Phylum Basidiomycota. Mushrooms are composed of three parts: stem, cap, and gill. Many species of mushroom lack stem. Gills are responsible for producing spores that cause the spread of mushrooms on its occupied surface.

Complete answer: Morels and truffles belong to the class Ascomycetes. Morels and truffles are those mushrooms that are used as food. These mushrooms are not easily available. Thus these are very costly. It is a very high source of iron and vitamins. Thus it can be said that the Morels and truffles are poisonous mushrooms is a wrong statement.
Yeast is a saprophytic fungus. It comprises a single cell thus called a unicellular organism. Yeast is responsible for converting the sugar into alcohol by releasing carbon dioxide and energy in absence of oxygen. This process is called fermentation.
Penicillium sp belongs to the class Ascomycetes, kingdom Fungi. It possesses more than one cell thus known as a multicellular organism. Penicillium is used to form an antibiotic called penicillin. Penicillin is used in the treatment of several respiratory problems like pneumonia, skin infection, gut infection, scarlet fever, etc.
Neurospora belongs to the Phylum Ascomycota, family Solanaceae. It is a type of fungi that are used in biochemical genetics.
So, the correct answer is “Option A”.

Note: Ascomycetes are also called sac fungi. It is known as the largest Phylum of the kingdom Fungi. It comprises more than 64000 species of fungi. These fungi possess spores that are nonmotile found in a reproductive structure named ascus or asci. These fungi are mainly parasitic and terrestrial.
