  • What is the primary carbohydrate storage product of fungi?
    Glycogen
  • What is the defining feature of the Chytrids within the Fungi? 
    Flagellum
  • Arbuscular Mycorrhizal Fungi belong to which Fungal phylum?
    Glomeromycota
  • The fusion of 2 nuclei within the reproductive cycle of a fungus is termed?Karyogamy
  • Asexual fungal spores may be termed?
    Anamorph
  • What is a soredium?
    Fungus / alga association
  • Protista as a taxonomic grouping are may best be described as...?
    Paraphyletic
  • Plasmodium falciparum is an apicomplexan that causes which disease?

    Malaria
  • Why is Dictyostelium discoidum an excellent model organism?
    Displays multicellular traits
  • In which taxonomic grouping would you find the pathogen Trichomonas vaginalis?
    Both Excavata and Parabasalids
  • •The primary carbohydrate storage product of fungi is glycogen (cf. starch in plants).
  • •Presence of ergosterol in membranes.
  • •A eukaryotic, heterotrophic organism devoid of chlorophyll that obtains its nutrients by absorption, and reproduces by spores.
  • •Most fungi have a mycelium composed of hyphae (sing. hypha) that elongate by tip growth. Contain chitin – N containing polysaccharide
  • •“Fungi” refers to the organisms in the Kingdom Fungi, the true fungi, also called the “Eumycota”
  • •Fungi are heterotrophs and absorb nutrients from outside of their body
  • •Fungi use enzymes to break down a large variety of complex molecules into smaller organic compounds
  • •The versatility of these enzymes contributes to fungi’s ecological success
  • •Apart from Chytrids have no flagella / motility so must be proximal for sexual reproduction.
  • Opisthokonta includes true fungi (Eumycota) and multicellular animals (Metazoa), as well as  Microsporidians
  • Animals and fungi share several key gene insertions and deletions.
  • Animal and fungal cells also share a structural feature distinguishing them from protists.
  • Fungi, animals, and their protistan relatives form the opisthokonts clade
  • ITS = Internal Transcribed Spacer –
    non-functional but easily amplified due to
    High copy number.
  • Kingdom Fungi can be broken down into 4 major phylums:
    • Zygomycota
    • Basidiomycota
    • Ascomycota
    • Deuteromycota
  • •Many molds and yeasts have no known sexual stageMycologists have traditionally called these
  • Chytridiomycota (chytrids)
    Flagellated spores
  • Zygomycota ( zygote fungi)
    Resisant zygosporangium as sexual stage
  • Glomeromycota (arbuscular mycorrhizal fungi)
    Arbuscular mycorrhizae formed with plants
