Document Summary

The a(cid:374)s(cid:449)e(cid:396) to the (cid:395)uestio(cid:374) is eithe(cid:396) (cid:1007) o(cid:396) (cid:1008). Audio recording started: 12:15 pm friday, january 26, 2018: the evolution of fungus, origin of fungi (picture on phone) Fungi are heterotrophs; eat for a living and digest their food to break it down. Sister group to the nucleariids: colonization of land. Colonized land ~470 million years ago (before plants!) ~100,000 species named 5 major groups within the fungi. Ii: nutrition and ecology, many are multicellular, mostly haploid lifecycle, no photosynthesis, heterotrophs-digest externally. Think: what does the above information mean about the environments that they must live in: body structure. Fu(cid:374)gi (cid:272)a(cid:374) (cid:271)e eithe(cid:396) : single cell=yeasts only. Or: multicellular (many cells), mycelium (pl. mycelia)=fungal body; grows in and around food source, hyphae-long branched filaments. But can be: predatory, mutualistic like the haustoria found in mycorrhizae, reproductive. # of mating types depends on # of alleles. Basic sexual life-cycle: two haploid (n) fungi.
