NEET BIOLOGY

Detailed explanation-1: -Familiar examples of sac fungi include morels, truffles, brewers’ and bakers’ yeast, dead man’s fingers, and cup fungi. The fungal symbionts in the majority of lichens (loosely termed “ascolichens") such as Cladonia belong to the Ascomycota.

Detailed explanation-2: -Common examples of ascomycetes include yeast, powdery mildews, cup fungi, morels, truffles, Neurospora, Aspergillus, Cladonia, Penicillium, Candida, Claviceps, etc.

Detailed explanation-3: -Most true yeasts belong to the Ascomycetes class. Few of the organisms of this phylum are baker’s yeast, Claviceps, Aspergillus, etc. There are around 64, 000 known species of the phylum Ascomycota.

Detailed explanation-4: -Ascomycota, also called sac fungi, a phylum of fungi (kingdom Fungi) characterized by a saclike structure, the ascus, which contains four to eight ascospores in the sexual stage.

Detailed explanation-5: -Ascomycota are either single-celled (yeasts) or filamentous (hyphal) or both (dimorphic). Yeasts grow by budding or fission and hyphae grow apically and branch laterally. Most yeasts and filamentous Ascomycota are haploid, but some species, Saccharomyces cerevisiae for example, can also be diploid.
