  1. 1. The shared derived character of all true plants, which gives the true plants their namesake.
  2. 6. one evolutionary advantage of flowers is that they bring the male and female gametes into close proximity, allowing for higher probability of _________, in plants that can self-pollinate
  3. 8. the group of fungi covered in class that do not produce mushrooms, and which have only a very brief, transient heterokaryotic stage
  4. 9. This tissue found in plants is responsible for movement of water and sugars throughout the plants; the evolution of which allowed for increased height and the development of roots.
  5. 13. The dominant “generation” observed in nature of mosses, and other non-vascular plants
  6. 16. The nutritional mode in which fungi acquire nutrition by killing living cells
  7. 17. an adaptation of many plants consisting of an embryo (developing sporophyte) packing with stored food, in a protection coat.
  8. 18. __________ fungi form symbiotic associates with plants, enhancing plant nutrient acquisition. This symbiosis is believed to have facilitated the colonization of land by plants.
  9. 19. the step of syngamy (fertilization) which involves the fusion of nuclei
  10. 20. the group of fungi covered in class that do not have a known sexual cycle.
  11. 23. the name for photosynthetic eukaryotes, other than plants
  12. 24. The general term for a fungal infection in animals
  13. 27. A specialized hypha which serves as a site of nutrient acquisition and transfer
  14. 28. A fungus that acquires nutrition from nonliving organic material, recycling nutrients in the environment, is referred to as a _____________.
  15. 30. The type of fungal hyphae which includes cross walls to protect the hypha from invasion and damage.
  16. 31. The nutritional mode in which fungi acquire nutrition from living cells
  17. 33. fungi are __________, in that they do not produce their own food, but acquire it from external sources
  18. 36. the genetic complement of the sporophyte generation
  19. 38. the group of fungi covered in class that produce reproductive structures known as mushrooms, and which can spend much of their life cycle in the heterokaryotic state
  20. 40. the “female” part of a flower, which is composed of a stigma, style, and ovary

  1. 2. This stage of a heterosporous life cycle arises from a spore, and is responsible for producing male gametes.
  2. 3. The theory that explains the plant transition to the sporophyte dominant life cycle by way of transition from alternation of isomorphic generations
  3. 4. The theory that explains the evolution of true leaves (aka megaphylls, euphylls)
  4. 5. symbiotic associates between photosynthetic microorganisms and fungi, primarily of the Ascomycetes
  5. 7. Referring to the condition in which plants produce two different kinds of spores: microspores, and megaspores; which develop into different gametophytes.
  6. 10. the condition in which fungi harbor two separate haploid nuclei in the same cell, unfused.
  7. 11. the genetic complement of the gametophyte generation
  8. 12. The “body” of a fungus, which is composed of a densely branched network of hyphae
  9. 14. The dominant “generation” observed in nature, of ferns and other vascular plants
  10. 15. In heterosporous plants, this spore line starts with a sporocyte, and eventually results in production of an egg.
  11. 18. This stage of a heterosporous life cycle arises from a sporocyte, and develops into an egg producing generation.
  12. 21. A fungus that interacts with other organisms in such a way that both organisms benefit from the interaction
  13. 22. The unicellular growth form of fungi, is referred to as _________.
  14. 25. the “male” part of a flower, which is composed of an anther and filament
  15. 26. small leaf-like projections of photosynthetic tissue which include extensions of vasculature, but are not true leaves
  16. 29. Referring to the condition in which plants produce a single kind of spore that typically develops into a bisexual gametophyte
  17. 32. In heterosporous plants, this spore line starts with a sporocyte, and eventually results in production of sperm.
  18. 34. The theory that mitochondria and chloroplasts originated as prokaryotic cells engulfed by a host cell.
  19. 35. The nutritional mode in which fungi acquire nutrition from living cells, and then transition to a stage in which they acquire nutrition by killing living cells.
  20. 37. The theory that explains the plant transition to the sporophyte dominant life cycle by way of interruption of an existing cycle, by mitosis at the zygote stage.
  21. 39. signaling molecules produced by fungi to communicate their mating types
