  1. How are spores produced in fungi?
    Asexually (mitosis) or sexually (meiosis)
  2. Which type of reproduction is prevalent in fungi?
  3. How do fungi eat?
    They are heterotrophs. They use absorptive modes of digestion
  4. How are fungal life cycles?
    Most have haploid life cycle and a few have alterations of generations
  5. How are new individuals form with fungi?
    Haploid spores
  6. How are the 3 body types of a fungi?
    Unicellular (yeast); filamentous, multicellular
  7. What is a hypha (pl. hyphae)
    One filamentous thread of cells joined end to end. All he hyphae are called a mycelium.
  8. What are fungal cell walls composed of?
    Chitin- a polysaccharide wall
  9. What are septae (sing. Septum)
    They are junction between individual cells in the hyphae
  10. Why are septae special?
    They allow for communication and movement of materials between cells
  11. What happens in the fungi with no septae
    The hyphae are then long strands with multiple nuclei and no separation between cells- aseptate of coenocytic
  12. What happens when he fungi releases digestive enzymes?
    They absorb the materials that are broken down by diffusion. Fungi are absorptive heterotrophs.
  13. In fungi, there is no such thing as
    Male or female; 1 to hundreds of ‘sexes’
  14. How is compatibility of individuals determined?
    They are determined by several loci, each with several alleles. MAT loci, 1 to hundreds of ‘sexes’
  15. What is the fungi that threatens frogs and other amphibians?
    Batrachochytrium dendobatidis
  16. How are spores with no flagella dispersed?
    Through the air (association with terrestrial evolution)
  17. What is the white fuzz on strawberries called?
  18. What is tempeh
    Soybeans fermented with rhizopous oligosporus
  19. What is zygomycosis?
    Infection that can enter through wounds and invade blood tissue; associated with untreated diabetes, extreme malnourishment, and burns; These can be worst fungal infections possible and can lead to death because of the difficulty in treating them.
  20. Brief overview on glomeromycetes
    No sexual reproduction known, obligate plant simbionts (aruscular mycorrhizae); large multinucleate asexual spores with layered walls.
  21. What is the hypothesis of glomeromycete fungi and origin of mycorrhizae in regards to land evolution in plants?
    It may be that plants were only able to colonize land because of evolution of fungi and mycorrhizae.
  22. How do yeast primarily reproduce?
  23. Which fungi reproduce asexually
  24. What is lichen morphology? What are 3 types?
    A controlled parasitism between ascomycetes and algea.
  25. How are ascomytes important in food industry?
    Morels and trffles
  26. How are fungi important in medicine
    Antibiotics (i.e. penicillin)
  27. What are dermatophytes
    Fungi that infect human skin
  28. What is a difference in basidiomycete life cycle from ascomycete?
    They lived in dikaryon stage longer and uncommonly participated in asexual reproduction.
  29. What are mushrooms
  30. What is so special about basidiomycetes?
    Many are saporophytes that can break down wood, they are some of the only organisms that are able to do this
  31. How is the mycorrhizae relationship between plants and ectomycorrhiae?
    They coat the surface and grow between the cells of roots
  32. What is the worlds largest eukaryotic organism
    A basidiomycete, 150k square meters
