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