The Basics • Like a plant • STATIONARY • Like an animal • HETEROTROPHIC • Like plants, animals, and protists • EUKARYOTIC • Cell walls made of • CHITIN
Basic Structure Hyphae- thin filaments making up a fungus (some called rhizoids help to anchor the fungus) Mycelium- mass of tangled filaments (hyphae); most of these are in soil or embedded in host’s tissue Fruiting body- reproductive structure; what you see Spores- thick-walled; located at tips of some hyphae; for reproduction
Reproduction • Fragmentation • Budding • Spores • Asexual • Sexual • Evolutionary advantage why? Fungi are classified according to the way they reproduce/ make spores
Zygote Fungi • Phylum Zygomycota • Example: bread mold • Specialized hyphae form 2 different organisms which fuse to form a zygote • Most are saprobes- feed on dead tissue and organic matter • Return valuable materials to soil & atmosphere
? Decomposers- break down complex organic matter into smaller components ? • Saprobes- feed on dead tissue and organic matter • Formerly called saprophytes • Examples: • Fungi • Bacteria • Detritivores- feed on non-living organic matter • Are scavengers the same thing? • Examples: • Earthworms • Mites • Millipedes • Some beetles Consumers?
Club Fungi • Phylum Basidiomycota • ex. Mushrooms, puffballs • Club-shaped basidia make spores • Saprobes • Some can be eaten
Sac/ Cup Fungi • Phylum Ascomycota • ex. Yeasts, mildews, molds • Specialized sac-like structure called an ascus produces spores • Heterotrophic parasites • Brewing, baking, penicillin, scientific research
Imperfect Fungi • Phylum Deuteromycota • Examples: Penicillium, those responsible for athlete’s foot & ringworm • No known sexual stage • Some used to make soy sauce and some blue cheeses
Lichens • A combo (2-part) organism often on rocks or tree trunks • 2 organisms are in a mutualistic relationship- both benefit • Fungus- provides protection, receives nourishment • Blue-green bacteria OR green alga- provides nourishment (it is autotrophic), receives protection • Uses • Food for animals • Create soil- the acid in a lichen can break through rocks
Mycorrizhae • Plants + fungi in a mutualistic relationship • Fungi get nutrients from plant roots • Plants get increased surface area from fungi, allowing them more water and minerals
