BIO153H5 Lecture Notes - Lecture 12: Ascus, Commensalism, Glomeromycota
Document Summary
Fungi constitute one of the 3 major lineages of multicellular terrestrial eukaryotes (the others being plants and animals). Many fungi are saprobes: break down dead organic material. 1 cell walls contain chitin (n rich polysaccharide), although some. Chytridiomycota also have cellulose can exist as single cells (yeasts); however, most are multicellular the fungal body is very simple; exists as a mass of hyphae (collectively called the mycelium) 2 types of hyphae (filaments): septate (cross-walls separate compartments with a nucleus, coenocytic (cytoplasm with many nuclei this is typical of the. Zygomycota) surface area > 300 cm2 in oregon: 860 ha; 2,600 years old! represent a symbiotic relationship between plants and fungi (occur in ~90% of plant species!) Fairy ring : formed by the outward growth of the mycelium; fruiting bodies appear at the edges. The body of a fungus may be simple, but due to its simplicity, it can also be huge! an individual honey fungus (armillaria ostoyae)
