Presentation Transcript

  1. Fungi Characteristics •       1) Unicellular and Multicellular Eukaryote 2) Heterotrophs and major Decomposers •      3) Most reproduce asexually by spores • 4) Cell wall made of Chitin • 5) Need moist, warm places in which to grow.

  2. Yeast is a single-celled fungus. • Fungi can either be unicellular or multicellular Witch’s Hat fungus is multi-cellular.

  3. Cap The cells of fungi are arranged in branching, threadlike tubes called hyphae Gills Hyphae

  4. Fungi are heterotrophs, but they cannot catch or surround their food. • So, how do they eat? • They have to live near or actually on their food supply • There are 3 ways that fungi get their food: • consumers (ex: bracket fungus) • Decomposers (ex: bread mold) • Parasites (ex: zombie ants)

  5. Insert Zombie Slide Video

  6. Reproduction • Most fungi reproduce asexually by making spores • Yeast cells reproduce asexually in a process called budding. • Fungi reproduce sexually when conditions are unfavorable.

  7. The Role of Fungi in Nature • Food and Fungi • Yeasts make bread rise • Molds are used to make cheese • Mushrooms on pizza yum! • Environmental Recycling • Decomposers—break down chemicals in dead organisms • Disease-Fighting • Penicillin—bread mold that produces antibiotics which kill bacteria. • Disease-Causing • Athlete’s foot • Ring worm

  8. Symbiosis: Lichens • A fungus and algae or autotrophic bacteria living together in a mutualistic relationship • Fungus provides shelter, water, and minerals • Algae/bacteria provide food
