Bio lecture 15 10/23/12 fungi chapter 26. Ex: athletes foot: cell wall composed of chitin, nitrogen containing polysaccharide, strong, flexible, durable. Gram negative peptidoglycan (lps: plants cellulose, habitats, terrestrial, ph optimal 5. 6, ranges 2-9. 3. temperature wide range: hypertonic environments, high salt/sugar concentration fungi will still grow, body organization fig 29-1, non-reproductive structures, hypha (hyphae) basic building block (basic unit) i. ii. Grow, secrete hydrolases: mycelium (mycelia) tangled mass of hyphae, types of hyphae i. ii. Dikaryotic cells (n+n) 2 nuclei are not identical because they came from opposite mating strains. Allows organelles and cytoplasm move between cells. Not nuclei: reproductive structures, spores, produced by either i. ii. Aerial hyphae (grow up and away from the surface of food) Allows for the dispersal of the spores. Supergroup unikont: kingdom fungi about a 100 species, 5 phyla table 29-1, fig 29-5 (evolution of important characteristics)
