Question

Ascomycetes are
A. Club fungi
B. Algal fungi
C. Pin moulds
D. Sac fungi

Answer 1

Ascomycetes are spore-shooting organisms. They are fungi that develop microscopic spores inside peculiar, elongated cells or sacs known as 'asci,' from which the group gets its name. Ascomycota is a division of the kingdom Fungi that forms the subkingdom Dikarya with the Basidiomycota. With approximately $64,000$ species, they constitute the biggest phylum of fungi. Humans rely on ascomycetes for medicinally significant chemicals like antibiotics, as well as for fermenting bread, alcoholic beverages, and cheese. Ascomycetes include Penicillium species found on cheeses and those that produce antibiotics for the treatment of bacterial infectious illnesses.

Complete explanation:
Option A: Basidiomycetes are known as club fungi because the sexual spore-bearing cells (basidia) resemble a little club. It can produce millions of spores on club-shaped basidia on the surface of its gills throughout its sexual cycle.
So, option A is incorrect.
Option B: Algal fungi get their name from their morphology, which is similar to that of algae. They are aquatic and have a thalloid shape. Phycomycetes is the scientific name for them.
So, option B is incorrect.
Option C: Mucorales is the largest and most well-studied zygomycete fungus order. Pin moulds are a term used to describe members of this order.
So, option C is incorrect.
Option D: Ascomycetes are known as sac fungi because they generate sexual spores (Ascospores) that are contained in a sac-like structure called an ascus.
Option D is correct.

Hence, Option D is the correct answer.

Note:
Ascomycota, is a fungus division whose members are known as Sac Fungi and generate spores in a special sort of microscopic sporangium known as an ascus. Yeasts, morels, truffles, and Penicillium are examples of sac fungi. Ascomycetes can be found in a variety of habitats, including freshwater and saltwater. Ascomycetes are parasitic on coral, algae, and other living species in watery environments. Some organisms, on the other hand, rely on decomposing materials to survive.
