Q.12
Question
The fungi that do not reproduce sexually used to be classified as ________.
a. Ascomycota
b. Deuteromycota
c. Basidiomycota
d. Glomeromycota
Step-by-Step Solution
VerifiedThe correct answer is (b) Deuteromycota
Deuteromycota do not reproduce sexually .
The kingdom Fungi contains five major phyla that were established according to their mode of sexual reproduction or using molecular data.
The five true phyla of fungi are the Chytridiomycota (Chytrids), the Zygomycota (conjugated fungi), the Ascomycota (sac fungi), the Basidiomycota (club fungi) and Glomeromycota.
b. Deuteromycota
Imperfect fungi—those that do not display a sexual phase—use to be classified in the form phylum Deuteromycota, , a classification group no longer used in the present, ever-developing classification of organisms. While Deuteromycota use to be a classification group, recent molecular analysis has shown that the members classified in this group belong to the Ascomycota or the Basidiomycota classifications
a. Ascomycota
The majority of known fungi belong to the Phylum Ascomycota, which is characterized by the formation of an ascus (plural, asci), a sac-like structure that contains haploid ascospores.
Asexual reproduction is frequent and involves the production of conidiophores that release haploid conidiospores. Sexual reproduction starts with the development of special hyphae from either one of two types of mating strains .
c. Basidiomycota
The basidiomycetes group is the group of fungi that gathers the representatives with the highest degree of structural complexity. Although fungi do not form true tissues, most species form macroscopic fruit with specialized hyphae organized in pseudotexes.
The lifecycle of basidiomycetes includes alternation of generations. Spores are generally produced through sexual reproduction, rather than asexual reproduction. The club-shaped basidium carries spores called basidiospores.
d. Glomeromycota
Glomeromycota form symbiotic relationships with the roots of trees.
