  1. KINGDOM FUNGI Chapter 20 page 529

  2. A-General Characteristics • Cell: Cell-Multicellular • Cellwall made of carb “chitin” • Food- Heterotrophs • Secrete enzymes to break down their food • Movement: None

  3. Use: Edible and some poisonous • Where: soil, water, mud, decaying plants/animals • Called: saprophyteslive on an organism and decompose it for food • Purpose: recyclers (along with bacteria)

  4. Examples: • Mushrooms • Yeast • Bread mold • Penicillium • Truffles • Athlete’s foot • Produce cheeses, yogurt and cottage cheese (examples to follow)

  5. Examples Cont’d

  6. Truffles Yeast British soldiers Fungal infection on the nail Yeast infection on the tongue Morels Cont’d

  7. Fungus on an agar plate Athlete’s Foot Mold on fruit Penicillium Cont’d

  8. Penicillium on an orange Cont’d

  9. Bread mold Cont’d

  10. Powerful Puffballs end

  11. B-Structure: 1-Hyphae-have enzymes (to digest food); thread-like filaments 2-Mycelium-network of hyphae; like roots 3-Chitin-carb in cell wall; strength & flexibility Examples to follow

  12. Examples Hyphae Mycelium made of hyphae

  13. Cap Stalk Gills Basidia: inside gills, small, lines inside Spores: attached to basidia

  14. C-Symbotic Relationship 1-Lichen fungus grows with algae For *Lichen provides structure and protection For *Algae provides food for fungus What type of symbiotic relationship?

  15. Fungus and Plants • Form mycorrhizae which means “fungus roots” For: Fungus gives plantwater & nutrients For: Plant gives fungus food What type of relationship?

  16. D-Reproduction 1-Asexual-offspring identical to parent no variation Example: Budding in which a piece of fungus breaks off and grows separate Picture next slide

  17. Yeast cells budding end

  18. 2-Sexual-offspring varies from parent Example: Spores in a fruit body (cap of a mushroom) -travels in the air -grows with right conditions (could be inhaled into lungs and cause infection)
