WebThe ascus, produced as a result of cytogamy, is a specialized ascomycote cell in which meiosis takes place, giving rise at maturity to eight cells, ascospores, in a linear arrangement. In most ascomycotes, the mature ascus bursts to release a cloud of spores; spores may travel as far as 30 cm. Multiple asci form within an apothecium or within ... WebIn most cases, an ascus holds 8 spores. However, the number can vary from one to several thousand [5].

Ascus is usually an elongated sac like structure, which contain normally 8 ascospores. Therefore, the correct answer is option B. Solve any question of Biological Classificationwith:- Webthese eight nuclei, and these cells become the ascospores. All eight ascospores are held within a single membranous sac called the ascus (pl. = asci). Many asci are contained within a larger fruiting body called the perithecium. In nature, the perithecium eventually ruptures and releases thousands of ascospores into the wind. Thus, the life
