  1. Fungi Of Lutheran High

  2. What is a fungi? • Usually they are popular • Have a sense of humor • Appreciates you

  3. Really- What is a fungi? • Eukaryotic Heterotrophs Majority are decomposers • Some are parasites • Some are good

  4. How do they eat? • Absorbtion • Thru cell wall/membrane • Secretion of enzymes • Break down food

  5. What do they look like? • Mycelium • Tiny filaments tangled together in mass

  6. What makes mycelium? • Hyphae • The tiny filaments • Made of Chitin or Cellulose

  7. Fungal Reproductionaka. Fungal luv Sexual & Asexual

  8. Asexual reproduction • Spores • Produced in Sporangia • Hyphae fragmentation

  9. Fungal Sexual Reproduction • (+) part and (-) part meet • Gametangium forms • Zygotes produced

  10. -mycota From greek “Mukes” word for mushroom

  11. Common Names • Water molds • White fuzz on fish “ich” • Potatoe blight

  12. Phylum: Zygomycota Common Molds

  13. Common Names • Bread molds • Cheese molds • Meat molds

  14. Zygomycetes • Chiton cell walls • Lack cross-walls • Except on reproductive structures

  15. Asexual reproduction • Root-like Hyphae “Rhizoids” • Stolons- put sporangia in air

  16. Sexual Reproduction • Gametangia- (+) & (-) together • Produce zygospore • Develops hyphae

  17. Phylum: Ascomycota Sac Fungi

  18. Common Names • Morels • Yeasts

  19. Ascomycetes • Cellulose cell walls • Cross-walls • Nuclei can transfer between walls

  20. Asexual reproduction • Hyphae called “Conidiophores” • Dust size spores

  21. Sexual Reproduction • Ascus is formed from (+) & (-) • Produce ascospores • Develops from ascus “tiny sac”

  22. The Ascus is edible Funguy says… YUM!

  23. Yeasts • Asexually do BUDDING -new yeast formed from old -this happens in bread

  24. Phylum: Basidiomycota Club Fungi

  25. Common Names • Mushrooms • Puffballs • Toadstools • Plant parasites

  26. Basidomycetes • Cellulose cell wall • Cross-walls • Cells will have two nuclei

  27. Asexual Reproduction • There isn’t a whole lot • Possibly conidia

  28. Sexual Reproduction • Basidium is structure • Spores germinate • 2 meet to make mycelium

  29. secondary mycelium is formed w/ 2 nuclei • These can grow for years • Fruiting body grows to form the mushroom cap

  30. Spores are released

  31. Phylum: Deuteromycota Imperfect Fungi

  32. Penicillium

  33. Athletes foot

  34. Ringworm

  35. Imperfect fungi • Given title due to lack of perfect understanding of their reproductive cycle

  36. Deutromycetes • Catch-all phylum • Similar to other mycota phyla

  37. Fungi in Nature Funguy Loves Camping!!!

  38. Where are they found? • Anywhere • Just need • Moisture • Food

  39. Fairy Ring

  40. Spore Release • Thousands at a time • Placement critical • Puffballs have most • Wind, rain…

  41. Stinkhorns • Use insects • Rotten meat smell

  42. Symbiotic Relationships • Lichens • Mycorrhizae

  43. Lichens • Symbiosis between algae & fungus

  44. Lichens • Fungus provides H2O • Algae provides food

  45. Fungi & Humans • Baking & Brewing • Stir-fry & Stewing • Poison & “coup”ing

  46. Stir-fry & Stewing • Mushrooms • Used for foods

  47. Poison & “coup”ing • Wild mushrooms can be poisonous • Emporer Claudius given “death caps”

  48. Disease • Athletes foot • Ringworm • Potato Blight • Wheat rust

  49. Potato Blight • Caused Potato Famine

  50. Wheat Rust St.Anthony’s fire
