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
Mycorrhizae Critical role in plant growth extends water absorption of roots without mycorrhizae with mycorrhizae EctomycorrhizaEndomycorrhiza
Reproduction Asexual budding in yeast Sexual spores spread by wind joining of + & – haploid spores haploid spores
hypha (n) haploid (2n) diploid mating strain FUSION of gametangia sporangium spores MEIOSIS Zygomycete (Bread Mold) Life Cycle
Basidiomycete Life Cycle FUSION of hyphae fruiting body spores gills lined with basidia basidium zygote (n) haploid (n + n) dikaryotic strain 2n (diploid)
