Document Summary
What"s a fu(cid:374)gus: the fungus hike, defining traits of fungi, general biology of the fungi types and ecology, microsporidia, chytridomycetes, zygomycetes, glomeromycetes, ascomycetes, basidiomycetes, fungal ecology: mutualists, saprobes, and parasites. Fungus is more closely related to animals than plants. Fungi branch off the clade with choanoflagellates and animals. Fungus is very diverse 6 main groups. Hyphae can be septate or coenocytic(indicates that cell separation is not very important to fungi. Mycelium :groups of hyphae that are bundled together. Fungi have cell walls with chitin(gives fungal cells their structure, insects use it also for their exoskelaton) Dikaryons form from the fusion of two haploid mating strains (many diff mating types) Fungal cells use nuclear division: the nucleus replicates and forms two copies, but the cell remains a single unit. Sexual stages are used to identify fungus, making it hard to finalize the fungal phylogeny. 1)mutualists(close w/ photosyn bacteria, ants, micorrhizal fungi that form complex associations w/ plant roots.
