Transcript of Kingdom Fungi -...
Basic Characteristics• Eukaryotic
• Most Multi-cellular (except yeast)
• Digestion is extra-cellular (outside body of fungus)
• Heterotrophs
• Most Detritivores /Some parasitic (ringworm)
Parts of a Fungi• Hyphae: single thread-
like strands of fungi, often underground
• Mycelium: branched network of hyphae
• Sporangium: asexual structure where spores are produced
• Spore: reproductive body
5 Types of Fungi• Deuteromycota: penicillin
• Mycorrhizae: mutualistic with plant roots
• Ascomycota: sac fungi (Morrel/yeast)
• Basidiomycota: Club Fungi (mushroom)
• Zygomycota: mold (fruit and bread)
Deuteromycota• “Imperfect” Fungi -
not easily classified
• Reproduce asexually
• Fungi that produces antibiotic penicillin
• Fungi that cause yeast infections and athlete’s foot
Mycorrhizae• Symbiotic with plant roots
• 80-90% plants have fungal relationships
• both plant and fungi benefit
• Increases surface area of plant roots
• more H20 uptake
• more mineral uptake
• What is fungal benefit?
• fungus gets sugar from roots!
Ascomycota• Mushrooms are rare in this group -
but it does include Morels, cup fungi, and “Dead man’s fingers”
Ascomycota• Ascomycota also includes
Lichens:
• symbiotic relationship between an algae and a fungus
Basidiomycota• MUSHROOMS!
• temporary fruiting body=reproductive body of fungus
• Hyphae and Mycelium is underground
• Parts common in this group:
• Cap (Basidia) = used for production and storage of spores
• Gills = for releasing spores
• Stype = stalk of mushroom
CAUTION!!!• NEVER EAT WILD MUSHROOMS! Many
edible mushrooms look identical to poisonous ones and require a microscope to look at spore prints to tell the difference!
