3. General characteristics  Classification criteria  eukaryotes  heterotrophs  feed by absorption  mostly multicellular  except unicellular yeasts  cell wall  chitin  rigid polysaccharide  sexual & asexual reproduction

4. Fungal Structure  Fungal body  mycelium  thread-like cells  hyphae  Cells  multiple nuclei  Cell wall  chitin  just like crab shells

5. Internal structure  Eukaryotic cells  long, thread-like cells  filamentous  incomplete divisions between cells  septum  multiple nuclei septum chitin cell wall nuclei pore

6. plant cell fungal hypha plant cell membrane plant cell wall Modes of Nutrition  Heterotrophic  secrete digestive enzymes  feed by absorption  predators  paralyzing prey  parasites  feeding on living creatures  decomposer  breakdown dead remains

7. Fungal Diversity Chytridiomycota Zygomycota Basidiomycota Ascomycota Fungi

8. 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

9. Mycorrhizae  Critical role in plant growth  extends water absorption of roots without mycorrhizae with mycorrhizae EctomycorrhizaEndomycorrhiza

10. Reproduction  Asexual  budding in yeast  Sexual  spores  spread by wind  joining of + & – haploid spores haploid spores
