Document Summary
Critical in terms of attacking and destroying food crops (see orange picture: penicillium mold on an orange. Range of organisms classified by fungus: any organism studied by mycologists, member of kingdom fungi (monophyletic group, defined by evolutionary relatedness) True fungi: sessile and heterotrophic species with cell walls that not member of plantae. Includes oomycetes and slime molds which aren"t true fungi. Various organisms that perform fungal like roles: sessile, heterotrophic, cell walls, true fungi (yellow, slime molds (green, oomycetes (stramenophile clade) Fungi are not monophyletic groups on their own: mostly going to study kingdom fungi, = artificial group in which organisms within have sessile, walled, heterotrophs. Major groups of fungi: water molds (oomycote, slime molds (myxomycota, chytrids (chytridomycota, zygomycetes (zygomycta, ascomycetes (ascomycota, basiomycetes (basidiomycota) Assimilate nutrients by absorption: fungus grows into its food, excretes digestive enzymes to break down proteins, nucleic acids, sugars within food. Small sized products are transported back into the fungal cell.
