Today s assignments

Today’s assignments:

  • Fungi Notes- go to MHS website and copy down notes from my blog (under files)

  • Survey lab


Fungi

Fungi

  • Characteristics

  • Eukaryotic

  • Most are multicellular – except yeasts

  • Nonmotile

  • Heterotrophic – acquire nutrients by absorption

  • Release digestive enzymes that digest plant cell walls and then grow into them

  • Mode of nutrition specializes fungi as: Saprophytes, parasites or mutualistic


Fungi1

Fungi

  • Classified according to their spore producing structure

  • Typical Fungi

  • Hyphae – individual filaments

  • Mycelium – masses or network of hyphae

  • Hyphae have cell walls made of chitin

  • Rhizoid – root like hyphae

  • Stolons – Hyphae that run along the surface of the food


Types of fungi

Types of Fungi

  • PHYLUM ZYGOMYCOTA

    • Zygomycetes

    • Terrestrial molds

    • Reproduce using sporangiophores that are capped by a sporangia containing spores.

    • Ex: Rhizopus stolonifer common bread mold


Types of fungi1

Types of Fungi

  • PHYLUM BASIDIOMYCOTA

    • Club fungi

    • Reproduce using club-shaped structure called basidia that form basidiospores.

    • Ex: mushrooms, shelf fungi


Types of fungi2

Types of Fungi

  • PHYLUM ASCOMYCOTA

    • Sac fungi

    • Reproduce by producing spores in an ascus- “little sac”

    • Ex: truffles, morels, yeast, dutch elm disease


Types of fungi3

Types of Fungi

  • PHYLUM DEUTEROMYCOTA

    • Imperfect fungi

    • Do not know how they reproduce

    • Ex: penicillin, ringworm


Fungi2

Fungi

  • Reproduction (handout 17.17)

  • Asexually – spores, fragmentation and budding

  • Sexually
