Ch. 31 Response Ch. 31: Describe the characteristics of the 5 fungal phyla. Why are fungi, plants, and animals classified in different kingdoms? Chytridiamycota: form uniflagellated spores called zoospores; mostly aquatic coenocytes, also in soil; most primitive fungi Zygomycota: usually terrestrial; in plasmogamy, they produce a very resistant zygosporangium where karyogamy and meiosis occur; can be microsporidia-parasites Glomeromycota: formerly thought to be zygomycetes; ecologically significant: arbuscular mycorrhizae Ascomycota: diverse habitats (marine to land) and diverse sizes (yeast to lichens); produce spores in asci, usually on large fruiting bodies called ascocarps Basidiomycota: club fungus; mushrooms, shelf fungi, puffballs; mainly decomposers;

Unformatted text preview: usually have long-lived dikaryotic mycelium that will form basidiocarps; karyogamy and meiosis occur in basidia; basidiospores released beneath basidiocarp Fungi, plants, and animals are classified in different kingdoms because they each have a different method of nutrition. Fungi are mainly heterotrophic decomposers meaning they get their nutrients from other organisms and organic compounds. Animals are also heterotrophs but are not decomposers and get nutrients through eating and digesting carbon-based organic compounds and other organisms. Plants have a different method of nutrition; they are a autotrophic and obtain nutrients through the process of photosynthesis. By absorbing sun light, oxygen, and water, plants are able to produce sugars....
