Across
  1. 3. The process by which organic substances move through the phloem of a plant
  2. 4. Hole through the testa where seed was attached to parent plant
  3. 5. A class of related plant hormones that stimulate growth in the stem and leaves, trigger the germination of seeds and breaking of bud dormancy, and stimulate fruit development with auxin.
  4. 9. A plant's response to light
  5. 15. The movement of seeds away from a parent plant
  6. 18. Transport Energy-requiring process that moves material across a cell membrane against a concentration difference
  7. 21. Plant cells associated with controlling neighbouring sieve cells
  8. 22. A type of plant that produces flowers and whose seeds are contained in fruit
  9. 25. An animal that carries pollen from one plant to another of the same species, enabling plants to reproduce.
  10. 27. Embryonic root
  11. 29. Plants that tolerate higher salt concentrations.
  12. 30. Substance in vascular plants that makes cell walls rigid
  13. 31. The transfer of pollen from male reproductive structures to female reproductive structures in plants
  14. 33. Embryonic plant tissue in the tips of roots and in the buds of shoots that supplies cells for the plant to grow in length.
  15. 34. Part of stem where growth occurs, contains meristem tissue that is capable of quick growth
  16. 35. The early growth of a seed. Requires water and warmth
  17. 36. Plants that have adapted to dry climates
  18. 38. The device used to measure the amount of transpiration occurring from a plant
  19. 39. Plants that flower when nights are longer than a critical length
  20. 40. Growth response of a plant toward or away from a stimulus
Down
  1. 1. A plant's response to seasonal changes in length of night and day.
  2. 2. Loading the active transport of sucrose into a sieve tube element
  3. 6. The major auxin produced in plants
  4. 7. these plants flower when nights are SHORTER than a critical length
  5. 8. Process by which a gene produces its product and the product carries out its function.
  6. 10. Non-living vascular tissue that carries water and dissolved minerals from the roots of a plant to its leaves
  7. 11. Aphids are green insects that feed on phloem sap. The stylet is their mouth part that penetrates the phloem vessel
  8. 12. Seed coat
  9. 13. Evaporation of water from the leaves of a plant
  10. 14. Growth response to gravity
  11. 16. A subdivision of flowering plants whose members possess an embryonic seed leaf made of two halves or cotyledons
  12. 17. Light receptor pigment that controls photoperiodism. There are 2 types - Pr (red-light absorbing) vs Pfr (infrared light absorbing). Pfr is the active form.
  13. 19. The fusion of a male gamete and female gamete to form a diploid zygote.
  14. 20. A method of rapidly cloning large numbers of plants using explants and tissue culture.
  15. 23. A plant hormone that promotes root formation and bud growth
  16. 24. Embryo shoot
  17. 26. An isotope that has an unstable nucleus and undergoes radioactive decay
  18. 28. An attraction between molecules of different substances
  19. 32. Found in phloem; stacked end to end; have holes so materials can get in and out of the phloem
  20. 37. Attraction between molecules of the same substance
