Document Summary

Lecture date/time: oct 6nd, 2015 / 10:35-11:25 am. Fungi foes: spores that grow through ants who"ve eaten it, rotting food, ring worms (skin), witch trials in the past possibly due to a common fungus growing on rye with hallucinogenic functions. Fungi friends: many benefits, mushrooms, yeast in beer bread, etc, decomposers. Fungi are absorptive heterotrophs (make their living by releasing enzymes that digest dead or decaying material, and suck in their nutrients (n, p, etc) from that material) ^most are decomposers (saprobes or saprotrophs) saprobes & saprotrophs. = organisms that derives nourishment from nonliving or decaying organic matter. Fungi are unique because they have both chitin (pronunciation: kye-tin), which is a poly glucosamine found in exoskeleton in many insects, as well as glucans, a polysaccharide found in plant cell walls. Most are multicellular (unicellular are known as yeast), mostly terrestrial, they produce spores asexually or sexually.
