BIOL 1108 Lecture Notes - Lecture 17: Dikaryon, Dikarya, Heterokaryon
Document Summary
Lacking plastids (hence, fungi are heterotrophic: storing energy in glycogen instead of starch, their cell wall is composed of chitin (like animals) Inability to capture prey or solid food particles by phagocytosis. Hyphae: filaments that comprise the body of fungi. Hypha: a single individual filament of fungal cells: filaments absorb nutrients though osmosis, nucleus found throughout the hyphae, everything is shared in hyphae, hyphal wall is not a cell wall , which is found in plants. Role of fungi: main decomposers of the planet, fungi as food, fungi as producers of medicines: antibiotics. Fungal phylogeny: dikarya group: 98% of all species fall into this group. (basidiomycetes, ascomycetes). Bio exam 2: chytrids: bd (amphibian killer, zygomycetes: small group, but very common. Black bread mold: glomeromycota: mutualistic relationship with plants and fungi mycorrhizal symbiosis, ascomycetes: yeasts, penicillin, cheeses, etc. Salem witch trials: predatory ascomycetes ants and bugs. Lichens are mutualistic associations between fungi and algae.
