EBIO 1220 Chapter Notes - Chapter 26.2: Marchantiophyta, Aglaophyton, Ascomycota
Document Summary
Concept 26. 2: though not closely related to plants, fungi played a key role in the colonization of. They formed symbiotic associations with fungi (as do most species living today). Fungi are heterotrophs: they cannot make their own food as plants and algae can. Fungi do not ingest (eat) their food, instead, they absorb nutrients from the environment outside of its body. Hypha (hyphae): one of many connected filaments that collectively make up the mycelium of a fungus. Prove a large sa across which absorption can occur. Mycorrhizae: the plant-fungal symbiotic association in which fungal hyphae transfer nutrients absorbed from soil to their plant partner. This benefit may have helped plants without roots colonize land. Fungi and animals are more closely related to each other than either group is to plants or to most other eukaryotes. Fungi are more closely related to several groups of single-celled protists, suggesting that the ancestor of fungi was unicellular.
