Slide Set 8 – Fungi Unicellular & multicellular  Cell walls are made of CHITIN  Mushrooms, toadstools, mold, morels, etc  Terrestrial, marine, and freshwater  HETEROTOPHS; but decompose food (not digest) and absorb  Parasites o Mycosis = fungal infection o Yeast infections, athletes foot, Pneumocystis pneumonia, fungal meningitis  Penicillin is made from Penicillium mold  Saccharomyces cerevisiae yeast o Bread o Wine o Beer  Lichens = symbiosis between a heterotrophic fungus & a photosynthetic alga or cyanobacterium  Chytridiomycosis o Fungal disease that helps frog’s fitness, makes them call for more females BODY STRUCTURE  Mycelium (below ground) o a network of branched filaments called HYPHAE that spread and increase surface area for absorption o The above ground structures (mushroom caps) are temporarily o The actual underground mycelium can live underground for years LIFE CYCLE Asexual and Sexual 1. Hyphae from 2 different parents meet and FUSE cytoplasm -> called PLASMOGAMY 1. Stinkhorn fungi- smells bad, flies come by and pick up spores which helps for dispersal 2. Puffballs – explode spores into the air, wind carries them 3. Chytrid fungi – aquatic spores that infect amphibians ORIGINS Ancestor Aquatic, unicellular, flagellated protest More closely related to animals than plants… (woah)  Chytrids  Zygomycetes  Glo
