Fungi are classified in their own kingdomThe study of Fungi is called Mycology
Heterotrophic Filamentous bodies Cell walls contain chitin Unique mitosis: nuclear membrane does
not disintegrate
Fungi are composed of hyphae Slender filaments Long string of cells divided by septa Septa do not form a complete barrier
How fungi obtain food Secrete digestive enzymes from hyphae Absorb and use molecules for energy Most fungi are decomposers: they live on decaying organisms. Decompose organic matter: leaves, branches, animal corpses,
animal waste Some fungi are parasites
they extract food from living organisms.
Commercially valuable
Yeast produce CO2 and alcohol:
brewing, baking, and wine-making
Produce pungent flavors of cheese
(i.e. camembert and roquefort)
Source of antibiotics (i.e. penicillin)
Lichens Key component of primary succession:
prepare environment for other organisms
Sensitive to pollution (particularly SO2)
Mycorrhizae Symbiotic relationship: plant roots + fungi Hyphae grow between soil particles and into
decomposing matter: absorb minerals Transfer minerals to plant roots
