Across
  1. 3. a complex, highly regulated process that requires new gene expression and involves the interactions of many signaling pathways,
  2. 5. the core structure of Cytokinin, also used in forming nucleotides of the nucleic acids.
  3. 7. bottom side of the leaf which had more stomata to control gas exchange and water loss
  4. 8. plant hormone that inhibits growth, closes stomata during water stress, promotes seed dormancy, leaf senescence
  5. 10. blue light receptor mediates seed de-etiolation, flowering, circadian rhythms and elongation.
  6. 12. Gibberellins promotes growth through cell __________ and division
  7. 17. blue light receptor mediates phototropism, flowering, seed de-etiolation, stomatal control, and chloroplast movement
  8. 18. plant hormones that inhibit root growth, stimulate seed germination, and inhibit senescence
  9. 19. plant growth response to light stimulus.
  10. 22. Alternate, Opposite, ____________ and Spiral are all types of phyllotaxy
  11. 23. red and far-red light receptor that mediates Shade avoidance, Seed de-etiolation, seed germination, flowering circadian rhythms and elongation.
  12. 25. plant hormone that promotes fruit ripening, controls abscission of flowers, fruits and leaves, and the retardation of lateral bud elongation
  13. 28. roots that arise from an organ other than the root—usually a stem, sometimes a leaf
  14. 30. the phenomenon whereby the main, central stem of the plant is dominant over other side stems
  15. 31. top side of the leaf that gathers sunlight and always forms on facing the meristem
  16. 32. the development of a seedling in the dark
  17. 33. plant growth response to gravity.
  18. 35. a transcription repressor instrumental in the biosynthesis of Gibberellins
Down
  1. 1. gene localized in the SAM region that encodes a transcription factor and is responsible for maintaining stem cell populations and identity
  2. 2. the immediate precursor in Abscisic Acid
  3. 4. All Plant hormones except Ethylene (which is not an acid) can be degraded through ___________
  4. 6. Auxin, Gibberellins and Abscisic Acid all have a _________________ as part of their chemical structure.
  5. 9. a chemical precursor to IAA (Auxin)
  6. 11. plant hormone that stimulates stem elongation and root growth, enhances apical dominance, functions in phototropism, gravitropism, and cell differentiation, and regulates fruit development.
  7. 13. starch-filled amyloplasts that act as sedimenting bodies, helping plant cells sense Gravity
  8. 14. light-sensitive proteins used by plants to sense and respond to light.
  9. 15. a complex fertilization mechanism of flowering plants. Occurs when there is a joining of a female gametophyte (megagametophyte, also called the embryo sac) with two male gametes (sperm)
  10. 16. plant hormones that promote seed and bud germination, leaf growth, and affect stem and internode elongation
  11. 20. GA biosynthesis is a ______________ pathway
  12. 21. a population of cells located at the tip of the shoot axis. It produces lateral organs, stem tissues and regenerates itself. It is the site of most of the embryogenesis in flowering plants. Primordia of leaves, sepals, petals, stamens and ovaries are initiated here at the rate of one every time interval
  13. 24. 2,4-D is an Auxin based _________ that kills only dicots and is the 3rd most commonly used in the USA
  14. 26. After Auxin binds with SCF(TIR1) and SCF (TIR1) ubiquinates the AUX/IAA transcriptional repressors, these repressors are degraded by a protein complex known as _______
  15. 27. Combined with an apoprotein, ______________ creates the Photoreceptor Phytochrome
  16. 29. Shoot Apical Meristem gene that negative regulates the Wushel gene ensuring that the meristem never changes size. Mutants without this gene have a larger Shoot Apical Meristem.
  17. 34. the most common, natural occurring form of Auxin
