Document Summary
Without nutrients from mycorrhizae plants would be stunted in their growth. Extreme nutrient poor soils (australia, south africa) Homology - similar due to shared ancestry. Clicker question list all the non-monophyletic groups: chytridiomycota, zygomycota, chytridiomycota. Dikarya is the only monophyletic group because all of its ancestors are on one branch. The other two groups are paraphyletic meaning they are not all equally related to each other: dikarya, zygomycota, chytridiomycota. Decomposers fungi are essential for the cycling of dead materials. Without decomposers, life as we know it would cease, nutrients would stay locked up. Symbiosis interspecific relationship (either positive or negative, mutualistic or parasitic) where partners are in direct contact. Plant pathogens (parasitic fungi) negative symbiotic relationship. About 30% of 100,000 known species of fungi are parasites, mostly on or in plants. Other fungi, such as rusts and ergots, infect grain crops. Cordyceps fungus the aunts that grow the fungus out of their head.
