General characteristics § Classification criteria eukaryotes u heterotrophs u § must feed off of others u mostly multicellular § except one-celled yeasts u AP Biology cell wall
Structure § Cells long thread-like cells u multiple nuclei u cell wall u § made from chitin w just like crab shells chitin cell wall septum pore nuclei AP Biology
How do Fungi get their Nutrition? fungal cells § Heterotrophs secrete digestive enzymes u absorb digested material into cell u § predators plant cell membrane w paralyzing prey § parasites w feeding on living creatures § decomposer w breakdown dead remains AP Biology Cool… Fungi live IN their food! Chocolate cake, anyone? plant cell wall
Ecological Roles § Decomposers u recycle nutrients § Symbiotic Relationships u lichen § fungi + algae § pioneer species in ecosystems § makes soil from bare rock u AP Biology mycorrhizae § fungi + plants § enables plants to absorb more water
Mycorrhizae § Critical role in plant growth u extends water absorption of roots without mycorrhizae Endomycorrhiza AP Biology Ectomycorrhiza with mycorrhizae
Reproduction § Asexual u budding in yeast § Sexual u gills on mushroom spores § spread by wind spores on gills AP Biology fungus growing in soil
Fairy Rings AP Biology
Importance of fungi to humans § Food production bread u beer, wine u § Medicine production u antibiotics penicillin AP Biology
