Give a comparative account of the classes of Kingdom Fungi under the following: (i) Mode of nutrition (ii) Mode of reproduction
(A) Phycomycetes- This institution of fungi consists of participants including Rhizopus, Albugo, etc. (i) Mode of nutrition They are obligate parasites on flora or are determined on decaying be counted including wood. (ii) Mode of duplicate Asexual replica takes vicinity via motile zoospores or non-motile aplanospores which are produced endogenously in sporangium. Sexual duplicate can be of isogamous, anisogamous, or oogamous type. It outcomes withinside the formation of thick-walled zygospore. (B) Ascomycetes- This organization of fungi consists of participants including Penicillium, Aspergillus,Claviceps, and Neurospora. (i) Mode of nutrition They are sporophytic, decomposers, parasitic or coprophilous (developing on dung). (ii) Mode of duplicate Asexual replica happens via asexual spores produced exogenously, consisting of conidia produced on conidiophores. Sexual replica takes vicinity thru ascospores produced endogenously in sac-like asci and organized interior ascocarps. (C) Basidiomycetes- This organization of fungi consists of participants which includes Ustilago,Agaricus and Puccinia. (i) Mode of nutrition They develop as decomposers in soil or on logs and tree stumps. They additionally arise as parasites in flora causing sicknesses which includes rusts and smuts. (ii) Mode of duplicate Asexual replica takes area generally thru fragmentation. Asexual spores are absent. Sex organs are absent however sexual replica takes region thru plasmogamy. It includes fusion of different lines of hyphae. The ensuing dikaryon offers upward push to a basidium. Four basidiospores are produced interior a basidium. (D) Deuteromycetes - This organization of fungi consists of individuals along with Alternaria, Trichoderma, and Colletotrichum. (i) Mode of nutrition Some individuals are saprophytes even as others are parasites. However, a big range act as decomposers of leaf litter. (ii) Mode of duplicate Asexual replica is the most effective manner of duplicate in deuteromycetes. It happens thru asexual spores called conidia. Sexual replica is absent in deuteromycetes.
