Question

A flask-shaped fruiting body of Ascomycetes is called as
A. Sclerotium
B. Apothecium
C. Cleistothecium
D. Perithecium

Answer 1

Hint: Ascomycota is the phylum of the Fungi Kingdom, the sub-kingdom of Dikaryon. Its members are typically called bag fungi or ascomycetes. It has more than 64,000 species and is the largest phylum of Fungi.

Complete answer: Ascocarps are classified into several groups, categorized as epigynous and hypogynous, depending on where they develop. Epigeous grows above the earth, while hypogynous grows underground. They are again categorized into the following categories on the basis of the arrangement of tissues. A sclerotium is a compact mass containing food reserves of hardened fungal mycelium. Sclerotia has a role to play in the survival of environmental extremes. Apothecium is an ascocarp of some lichens and fungi that are disk-shaped or cup-shaped. This type of variety is usually a type of closed body, it has no outside opening and is covered by a lot of hyphae and can be called appendages. It consists of asci which are located inside the inner cavity. Cleistothecium is a globose ascocarp that is closed. Usually, this type of fungus is sessile and fleshy in nature. It mainly consists of three sections, Hymenium, Hypothecium, and Excipulum, where the asci are present in the hymenium layer. Perithecium is structured in the form of flasks, where ascospores escape through a pore or ostiole. This type is flask-like and has a small opening from which ascospores are spread, a cylindrical shape of this variety, where they are goblet or pear in others.
Hence, option D is the correct answer.

Note: Ascomycetes are of specific use to people as medicines of restoratively significant mixes, for example, anti-infection agents, for fermenting bread, mixed drinks and cheddar or cheese. Penicillium species on cheese and those that create antitoxins for treating bacterial irresistible illnesses are instances of ascomycetes.
