Is its own mono clade w 6 main groups. More closely related to animals than plants. Branch off clade w choanoflagellates (protist) and animals [anc likely mobile] Facts about fungi: can have number of cell types/ be uni. Multi (most fungi were at some point in life cycle) Filamentous: have hyphae(long chains of cell-like structures) Fungal body: hyphae can be septate/coenocytic divided by septa cross pieces. Septate: pores in septaallow movement b/t compartments. Coenocytic: have mycelium (groups of hyphae that in hyphae [multinucleate] can be either digestive/reprod: hetero that absorb nutrients. Use ext digestion/absorptive hetero: secrete dig enzymes into area to digest food, then absorb organic material. Dikaryon: special multinucleate cell housing 2 nuclei in septate fungus.
