AP Biology plant cell fungal hypha plant cell membrane plant cell wall Modes of Nutrition Heterotrophic secrete digestive enzymes feed by absorption parasites feeding on living creatures predators paralyzing prey decomposers breakdown dead remains Fungi live IN their food! It’s like you living in Chocolate cake!
AP Biology Fungal Diversity Chytridiomycota Zygomycota Basidiomycota Ascomycota Fungi
AP Biology Ecological Roles Lichens are fungi that have discovered agriculture! Decomposers recycle nutrients Symbiotic Relationships lichen fungi + algae cyanobacteria or green algae pioneer species in ecosystems makes soil from bare rock mycorrhizae fungi + plants live in & amongst plant roots enables plants to absorb more water & nutrients
AP Biology Mycorrhizae Critical role in plant growth extends water & nutrient absorption of roots without mycorrhizae with mycorrhizae EctomycorrhizaEndomycorrhiza
AP Biology Reproduction Asexual budding in yeast Sexual spores spread by wind joining of + & – haploid spores haploid spores
