Document Summary
Origin of fungi evolved from a unicellular, flagellated ancestor. Animals, fungi, and related protists form opisthokont clade. Animals and fungi may have diverged into separated lineages 1-1. 2bya. Nucleariids heterotrophic amoebas (protists) ancestors of the fungi. Colonization of land fungi colonized land earlier than the plants which colonized land ~470mya so before plants, life on land was green slime made of: cyanobacteria prokaryotes algae protists small heterotrophs like fungi. Fig 31. 10 diverse lineages: fungal lineages diversify >1. 5 million species of fungi (5 major groups) Nutrition and ecology nearly all of the fungi are multicellular fungi are not photosynthetic even though some of them look green, they don"t have chlorophyll and don"t have chloroplasts and therefore they are not plants. They are all absorptive heterotrophs relies on organic materials produced by others. Main types of fungi in terms of how they acquire their nutrients: Decomposers: an organism that breaks down and in the case of fungi, absorb nutrients from nonliving organic material.
