Presentation Transcript

  1. Kingdom: Fungi

  2. Kingdom Fungi Characteristics • Is fungi autotrophic or heterotrophic? • Is fungi eukaryotic or prokaryotic? • Is fungi unicellular or multicellular? • Does fungi have a cell wall? BONUS: What is it made of? Except YEAST YES! Chitin

  3. Where do fungi grow? Warm, damp, dark places

  4. Basic Structure of Fungi • Unicellular Yeast • Multicellular • Hyphae threadlike filaments • that form a network called mycelium Most of the Fungi is found underground!

  5. Importance of Fungi • Decompose organic matter (recycle nutrients) • Food (mushrooms, bleu cheese, soy sauce, etc…) • Baking and brewing (by alcoholic fermentation) • Soil formation • BioTechnologyused to make antibiotics and other drugs Cellular respiration with no oxygen

  6. Penicillin Alexander Fleming, 1928

  7. 3 Feeding relationships of Fungi • Decomposers- absorb and recycle nutrients from decaying matter • Parasitism– Fungi benefits and the affected plants or animal is harmed • Mutualism-both the fungi and the photosynthetic organism benefit

  8. Fungi as Decomposers:Help break down decaying matter and recycle nutrients

  9. Fungi as ParasitesParasitism– Fungi benefits and the affected plants or animal is harmed • Animals • Athlete’s foot • Ringworm • Candidiaalbicans

  10. Fungi as Parasites • Plants • Rust • Smut • Mildew • Can result in massive crop losses

  11. Parasitic Fungi

  12. Mutualistic Fungi: Mutualism-both the fungi and the photosynthetic organism benefit Examples: • Mycorrhizaesymbiosis between Fungus + Plants • How do they benefit each other? • Plant provides food by photosynthesis • Fungi increase water and mineral intake

  13. Mutualistic Fungi • Lichenssymbiosis betweenFungus + Algae – essential in the formation of soil • How do they benefit each other? • Algae provides food by photosynthesis • Fungi provides water and minerals

  14. Reproduction • Asexual • Fragmentation • Budding • Sexual • Fruiting body • Spores • Dispersed by wind, water and animals

  15. Fun Fact! • Morels & truffles are considered edible fungi delicacies…and are very expensive!! TRUFFLES $500-$6000 per pound! MORELS $50-$100 per pound
