Question

Asci is formed in:
A. Ascobolus
B. Saccharomyces
C. Penicillium
D. All of the above

Answer 1

Ascomycetes are commonly known as spore shooters. They are fungi that develop microscopic spores inside special, elongated cells or sacs known as 'asci' that give their name to the group. The dominant mode of propagation in the Ascomycota is asexual reproduction and is responsible for the rapid spread of these fungi into new regions.

Complete answer: In ascomycete fungi, asci is the sexual spore-bearing cell produced. Typically, each ascus produces eight ascospores (or octads), formed by meiosis, followed by a mitotic cell division in most organisms. Asci, however, can occur in numbers of one in some genera or species. Asci are produced from the Kingstone Fungi Ascomycetes. The sexual spores are called ascospores, which are formed in sac-like structures called asci-like structures endogenously (singular ascus). These asci are arranged in various forms of ascocarps, called fruiting bodies. Antheridium is the male sex organ of Ascomycetes, and the female sex organ of Ascomycetes is called Ascogonium. Ascobolus , Saccharomyces , Penicillium , Aspergillus and are examples of Ascomycetes.
So, option D is the correct answer.

Note: By bursting at the top, asci usually release their spores, but they may also digest themselves, releasing the ascospores either passively in a liquid or as a dry powder. Discharging asci, either a pore or an operculum typically has a specially differentiated tip called puffing. For the classification of Ascomycota, the shape of the ascus, the capsule containing the sexual spores is significant.
