9. Give a comparative account of the classes of Kingdom Fungi under the following:
(i) mode of nutrition
(ii) mode of reproduction
A comparative account of the classes of Kingdom Fungi is as follows:
Phycomycetes | Ascomycetes | Basidiomycetes | Deuteromycetes | |
Mode of nutrition | These are obligate parasites or saprotrophs i.e. grow on dead, decaying matter. | These are saprophytic, decomposers, parasitic and coprophilous ( growing on dung) | These have saprotrophic nutrition. They are decomposers also. | Deuteromycetes can be saprophytic, decomposers or parasitic. |
Mode of reproduction | Asexual reproduction takes place through the formation of zoospores (motile) or aplanospores (non-motile). Sexual reproduction takes place via gametangial copulation. | Asexual reproduction takes place through conidia formation. Sexual reproduction takes place by ascospore formation | Asexual reproduction is absent. Sexual reproduction occurs via basidiospore formation. | Mode of reproduction is always asexual through the formation of conidia. Sexual reproduction has not been identified in this group. |
