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