General characteristics

General characteristics

  • Classification criteria

    • eukaryotes

    • heterotrophs

      • feed by absorption

    • mostly multicellular

      • except unicellular yeasts

    • cell wall

      • chitin

        • rigid polysaccharide

    • sexual & asexual reproduction


Fungal structure

Fungal Structure

  • Fungal body

    • mycelium

      • thread-like cells

      • hyphae

  • Cells

    • multiple nuclei

  • Cell wall

    • chitin

      • just like crab shells


Internal structure

Internal structure

chitin cell wall

septum

  • Eukaryotic cells

    • long, thread-like cells

      • = HYPHAE

    • incomplete divisions between cells

      • septum

    • multiple nuclei

pore

nuclei


Modes of nutrition

Modes of Nutrition

fungal hypha

  • Heterotrophic

    • secrete digestive enzymes

    • feed by absorption

      • predators

        • paralyzing prey

      • parasites

        • feeding on living creatures

      • decomposer

        • breakdown dead remains

Ecological roles

Ecological Roles

  • Decomposers

    • recycle nutrients

  • Symbiotic Relationships

    • lichen

      • fungi + algae

      • pioneer species in ecosystems

      • makes soil from bare rock

    • mycorrhizae

      • fungi + plants

      • enables plants to absorb more water


Mycorrhizae

Mycorrhizae

  • Critical role in plant growth

    • extends water absorption of roots

withoutmycorrhizae

withmycorrhizae

Endomycorrhiza

Ectomycorrhiza


Reproduction

Reproduction

  • Asexual

    • budding in yeast

    • mycelium produces spores via mitosis

      • spread by wind

  • Sexual

    • joining of + & – haploid mycelium form diploid zygote

    • Zygote makes haploid spores via meiosis
