Document Summary
Breaking down dead organic material into simple compounds that plants can absorb. A number of plant and human diseases: recently diverged from animals in evolutionary tree, extremely beneficial. 90% of plants form mycorrhizae: fungal associations with roots that helps absorb water and minerals: have evolved unique modes of dispersal. Pilobolus: forms spore structure at the top, pressure then explodes at 25 m/s (dung cannon fungus: the good and the bad. Used for food or in manufacture of food (bread, some cheeses, alcoholic beverages) Produce important drugs: antibiotics (penicillin, cephalosporin), cyclosporin (anti-rejection dug) Growth of bacteria on the agar in a culture dish has been inhibited by penicillium notatum. First antibiotic = penicillium mold that inhibited staphylococci (fleming) Ancient treatments for infections included using moldy bread. Cause significant diseases of plants: 5 phyla in the kingdom (changes over time) 1-2 million species, very diverse: morphology. Some fungi are dimorphic: can grow as both yeast-like cells and mold-like cells.
