Across
  1. 2. 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.
  2. 3. Alternate, Opposite, ____________ and Spiral are all types of phyllotaxy
  3. 5. plant growth response to light stimulus.
  4. 11. the immediate precursor in Abscisic Acid
  5. 13. 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 _______
  6. 16. 2,4-D is an Auxin based _________ that kills only dicots and is the 3rd most commonly used in the USA
  7. 18. plant hormones that promote seed and bud germination, leaf growth, and affect stem and internode elongation
  8. 19. Combined with an apoprotein, ______________ creates the Photoreceptor Phytochrome
  9. 20. blue light receptor mediates phototropism, flowering, seed de-etiolation, stomatal control, and chloroplast movement
  10. 23. 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
  11. 25. plant growth response to gravity.
  12. 27. roots that arise from an organ other than the root—usually a stem, sometimes a leaf
  13. 28. top side of the leaf that gathers sunlight and always forms on facing the meristem
  14. 29. plant hormones that inhibit root growth, stimulate seed germination, and inhibit senescence
  15. 30. the most common, natural occurring form of Auxin
  16. 31. plant hormone that stimulates stem elongation and root growth, enhances apical dominance, functions in phototropism, gravitropism, and cell differentiation, and regulates fruit development.
  17. 32. red and far-red light receptor that mediates Shade avoidance, Seed de-etiolation, seed germination, flowering circadian rhythms and elongation.
  18. 34. the core structure of Cytokinin, also used in forming nucleotides of the nucleic acids.
Down
  1. 1. Gibberellins promotes growth through cell __________ and division
  2. 4. plant hormone that promotes fruit ripening, controls abscission of flowers, fruits and leaves, and the retardation of lateral bud elongation
  3. 6. light-sensitive proteins used by plants to sense and respond to light.
  4. 7. gene localized in the SAM region that encodes a transcription factor and is responsible for maintaining stem cell populations and identity
  5. 8. 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)
  6. 9. Auxin, Gibberellins and Abscisic Acid all have a _________________ as part of their chemical structure.
  7. 10. GA biosynthesis is a ______________ pathway
  8. 12. a complex, highly regulated process that requires new gene expression and involves the interactions of many signaling pathways,
  9. 14. starch-filled amyloplasts that act as sedimenting bodies, helping plant cells sense Gravity
  10. 15. the phenomenon whereby the main, central stem of the plant is dominant over other side stems
  11. 17. the development of a seedling in the dark
  12. 21. blue light receptor mediates seed de-etiolation, flowering, circadian rhythms and elongation.
  13. 22. plant hormone that inhibits growth, closes stomata during water stress, promotes seed dormancy, leaf senescence
  14. 24. All Plant hormones except Ethylene (which is not an acid) can be degraded through ___________
  15. 26. a chemical precursor to IAA (Auxin)
  16. 28. bottom side of the leaf which had more stomata to control gas exchange and water loss
  17. 33. a transcription repressor instrumental in the biosynthesis of Gibberellins
