Presentation Transcript

  1. Kingdom Fungi Study of Fungi = Mycology • Common Characteristics: • Eukaryotic • No chlorophyll and are heterotrophs • Cell walls of cells are made of chitin • Most are multicellular. Only unicellular fungus is yeast. • Digest food outside their bodies and absorb • the nutrients through their cell walls. • Most are saprophytes, others are parasites. • Reproduction – asexually (cells or hyphae break off and begin to grow on their own, forming of spores or budding as in yeast) or sexually through gametes that combine to form a zygote

  2. Structure and Function of Fungi: All fungi are multicellular except for yeasts. Multicellular fungi are composed of thin filaments called hyphae.

  3. Many hyphae tangled together into a thick mass is called the mycelium

  4. The part of the mushroom that we see is called the fruiting body. This is the reproductive structure growing from the mycelium in the soil beneath.

  5. Classification of Fungi Classified according to their structure and the method of reproduction. • 4 Main phyla: • Zygomycota (Common molds) • Ascomycota (Sac Fungi) • Basidiomycota (Club Fungi) • Deuteromycota (Imperfect Fungi)

  6. Chytridiomycota – Phylum of Primitive Fungi/Chytrids • Smallest fungi • Mostly aquatic • Produces spores with flagella • Some are decomposers • Others are parasites of protists, plants or • animals • Example: Ich

  7. Zygomycota (Common molds or bread molds) • Terrestrial • Have 2 kinds of hyphae: Rhizoids and Stolons • Reproduce sexually through zygospores • Examples: Bread mold and Black mold

  8. Ascomycota (Sac Fungi) • Largest phylum • Named after the reproductive • structure (ascus) which contains the spores.

  9. Examples Truffles Morels

  10. Cup fungi Yeast

  11. Ringworm Athlete’s foot

  12. Basidiomycota (Club Fungi) • Named after the spore producing structure • which is the basidium found in the cap. It looks • like a club.

  13. Complex life cycle • They have a part above ground and a part below • ground. • Mushroom is the fruiting body. • When the cap opens, billions of spores are released.

  14. Examples: Bracket or Shelf fungi

  15. Mushrooms

  16. Smuts fungi Rusts fungi Cause disease in plants

  17. Deuterymycota – Imperfect fungi • Fungi that cannot be placed in other phyla because researchers have never been able to observe a sexual phase in their life cycles.

  18. Example: Penicillium
