1. Domain Eukarya

3. * Fungi and Animals (metazoa) form a monophyletic group * Common ancestor = Opisthokonts * Single celled organisms with posterior flagella * Based on molecular evidence

7. Includes: Kingdom Fungi Kingdom Animalia Diverged about 1.5 bya

9. * Closest protist ancestor: amoebozoans * Shared dreived triat of all Opisthokonta = single posterior flagellum ( lost in all but most primitive fungi, present in sperm of animals

10. * Kingdom Fungi (first fossils 460 mya) * Shared derived traits: * 1) chemoheterotrophs that absorb food * * 2) reproduce by spores * 3) cell walls with chitin

11. * Fungus bodies.. * * most multicellular ( unicellular = yeast) * cells form long chains = hyphae * cells surrounded by tubular cell wall(chitin) * septa divide hypha into cells * holes in septa so cytoplasm flow btwn cells

12. * Hyphae can interweave to form a solid body * Body formed of hyphae = mycelium

13. * Fungus nutrition… * All feed by absorbing food * exoenzymes secreted into environment * (extracellular digestion) * saprobes = decomposers * parasites * mutualistic symbionts = mycorrhizae * a) ectomycorrhizal fungi * b) endomycorrhizal fungi * c) lichen

14. * Fungi deliver ions to plant * Plant shares sugars * Hyphae increase surface area

15. * Fungal Reproduction…
