Chapter 24: Fungi I. Characteristics A. Fungi are heterotrophs that must obtain organic compounds that other organisms have already synthesized B. Saprobes feed on and thus decompose organic wastes and remains C. Parasites withdraw nutrients from the tissues of a living host D. Mycelium are a mesh of branched filaments in multicelled kinds of fungi E. Hypha are each filament and have a good surface-to-volume ratio for absorbing nutrients II. Fungal Groups A. Chytrids and microsporidians are the most ancient intracellular parasites and produce flagellated spores (basal groups) B. Zygomycetes produce sexual spores and rapidly colonize substrates by dispersing asexual spores from the sacs of specialized hypha C. Sac fungi/Ascomycetes – sexual spores produced in a linear fashion in sacs D. Club fungi/Basidiomycetes - make sexual spores in club-shaped structures and are dispersed by air currents (haploid) E. Imperfect fungi have unknown sexual spores III. Fungal symbionts A. Endophytic fungi are symbionts that live inside leaves and stems of plants
