Biology 21.2

  1. 1. Classification of Fungi 21.2<br />
  2. 2. Zygospore <br />Resting spore that contains zygotes formed during the sexual phase of a mold’s life cycle.<br />
  3. 3. Rhizoid<br />In fungi, a root like hypha that penetrates the surface of an object; in mosses, a long, thin cell that anchors the moss to the ground and absorbs water and minerals from the surrounding soil.<br />
  4. 4. Stolon<br />In fungi, a stem like hypha that runs along the surface of an object; in plants, a long, trailing stem that produces roots when it touches the ground.<br />
  5. 5. Gametangium <br />Gamete-producing structure found in mold.<br />
  6. 6. Conidium <br />Tiny fungal spore that forms at the tips of specialized hyphae in ascomycetes. <br />
  7. 7. Ascus<br />Structure within the fruiting body of an ascomycetes in which two of different mating types fuse.<br />
  8. 8. Ascospore <br />Haploid spore produced within the ascus of ascomycetes.<br />
  9. 9. Budding <br />Asexual process by which yeasts increase in number; process of attaching a bud to a plant to produce a new branch. <br />
  10. 10. Basidium<br />Spore-bearing structure of a basidiomycetes. <br />
  11. 11. Basidiospore <br />Spore in basidiomycetes that germinates to produce haploid primary mycelia.<br />
  12. 12. Key Concept<br />Zygonmycetes have life cycles that include a zygospore.<br />
  13. 13. Key Concept<br />The phylum Ascomycota is named for the ascus, a reproductive structure that contains spores.<br />
  14. 14. Key Concept<br />The Deuteromycota are fungi that cannot be placed in other phyla because researchers have never been able to observe a sexual phase in their life cycles.<br />
