1. FUNGI

2. Fungi General Characteristics eukaryote absorptive heterotroph - saprobe or parasite cell walls made of chitin multicellular (except for yeast) reproduce with spores

3. Structure hyphae –filaments of cells, tubes with many nuclei mycelium –(tissues) branches of hyphae; main body of fungus rihizoids –root like hyphae that anchor fungus stolons –stem-like hyphae that run along surface of a food source Fungi

4. Structure hyphae Fungi

5. Structure mycelium Fungi

6. Fungi are classified based on their reproductive structures (how they produce spores) Fungi

7. Digestion –extracellular digestion enzymes are secreted into food source food source is digested by enzymes nutrients are absorbed by fungus Fungi

8. Life Cycle fungal spores dispersed –Spores that reach food source – germinate hyphae penetrate into food –Nutrients are absorbed mycelium grows from the food –fruiting body is made releases spores Fungi

9. Phylum Zygomycota common name - common molds ex – bread mold reproduction –asexual – spores from sporangium –sexual - zygospore forms when hyphae of different sexes fuse together; thick walled zygospore is formed uses – parasite, saprobe Fungi

10. Phylum Basidiomycota common name – club fungi ex – mushrooms, shelf fungi, smuts, rusts, puffballs reproduction –basidiospores –basidia – club shaped structure where spores form on gills uses – many are edible; plant disease; poisonous (toadstools) Fungi

11. smutsrusts stinkhornshelf fungi Fungi

12. puff balls mushrooms Fungi

13. Phylum Ascomycota common name – sac fungi ex – yeast, powdery mildews, morels reproduction –asexual – conidiophores (clusters of spores) –sexual – ascospores produces in ascus (sac like structure) uses – brewing, baking, research, plant diseases, some are edible Fungi

14. Morels YeastPowdery mildews Fungi

15. Phylum Duteromycota common name – imperfect fungi ex – penicillium, ring worm, athlethe’s foot, jock itch reproduction –only asexual uses – penecillin / antibiotics, soy sauce, bleu cheese, citric acid Fungi

16. ring worm Fungi

17. Athlete’s foot (ring worm) Nail fungus (ring worm) Fungi

18. Phylum mycophyta common name – lichen mutualistic relationship –fungus & green algae, neither could live alone –algae provides food, fungus provides protection and minerals reproduction (skip) uses – food for animals, pioneer species, starts soil in some places Fungi

19. lichen Fungi
