Detailed explanation-1: -Sexual reproduction leads to the development of ascospores, which are produced in a specialized saclike structure known as an ascus. Asexual reproduction consists of the production of conidia, from a generative or conidiogenous cell.

Detailed explanation-2: -An ascus is a saclike structure enclosing the ascospores. The type of ascus is fundamentally important in the classification of ascomycetes. In discoid fungi the ascus may be operculate, opening with a lid or similar discharge mechanism, and relatively thin-walled, or it may be inoperculate and thick-walled.

Detailed explanation-3: -ascus, plural asci, a saclike structure produced by fungi of the phylum Ascomycota (sac fungi) in which sexually produced spores (ascospores), usually four or eight in number, are formed.

Detailed explanation-4: -It is the largest phylum of Fungi, with over 64, 000 species. The defining feature of this fungal group is the “ascus” (from Ancient Greek (askós) ‘sac, wineskin’), a microscopic sexual structure in which nonmotile spores, called ascospores, are formed.

Detailed explanation-5: -Ascus is the sac like body formed in most members of Ascomycetes. It bears the product of sexual fusion – the diploid nucleus. The diploid nucleus undergoes meiosis and mitotic divisions to produce haploid nuclei that aggregate with the cytoplasm to form haploid ascospores.
