Document Summary

31. 8: the clade starts with a unicellular, flagellated (*single flagella*) ancestor, *where the name comes from, sister taxa to fungi is the nucleariids. Colonization of land: fungi on land before plants (land plants ~470 mya, before plants green slime land organism. Diverse fungi lineages: ~100,000 identified species could be up to 1. 5 million, 5 major groups: Nearly all multicellular: common ancestor of all fungi is multicellular. Not photosynthetic: no chlorophyll, no chloroplasts not plants. Absorptive heterotrophs: heterotrophs, but do not ingest food and digest internally animals, secrete hydrolases (hydrolytic enzymes) process of hydrolysis, polymers monomers externally, absorb small organic molecules. Resource acquisition: hypha digestive enzyme secreted substrate digested organic matter absorbed repeat. Why fungi grow best in moist environments. 3 main lifestyles: decomposers: absorb nutrients from non-living organic material. Extremely important in ecological nutrient cycles: parasites: absorb nutrients from cells of living hosts. Ex: athlete"s foot: mutualists: absorb nutrients from living host, but host benefits from this.
