Across
  1. 2. A ring that defines the endodermis and allows for selective intake of nutrients into the vasculature of plants
  2. 4. The stem of seedlings
  3. 5. The incorporation of a compound into a sugar or protein, often for storage.
  4. 6. A small pore in the ovule that serves as the entry point for pollen to fertilize the egg.
  5. 7. A small string of amino acids added by a E3 Ubiquitin Ligase that mark a protein for degradation via a 26S Proteosome
  6. 10. The process where a seed must go through a series of process-drying out the seed-before it breaks dormancy
  7. 13. The region of a leaf petiole or fruit pedicel that forms to allow clean breakage
  8. 15. The pollen producing structure on stamen
  9. 18. The plant hormone that is comprised of 4 rings. It plays a role in internode length, seed germination, and fruit formation.
  10. 20. The precursor to auxin
  11. 21. The occurrence when seeds germinate while still in the fruit
  12. 24. The photoreceptor that is sensitive(photo-irreversibly) to blue light and regulates seedling de-etiolation, circadian rhythm, and flowering
  13. 27. The collection of female reproductive organs in a flower
  14. 29. The tendency of a shoot to remain unbranched
  15. 30. The ability of somatic cells to differentiate and mature into a complete organism in plants
  16. 31. The side of the leaf that is farthest from the SAM (Shoot Apical Meristem)
  17. 32. The phenomenon where multiple gene code for proteins with similar/identical functions
  18. 33. The collection of male reproductive organs in a flower
  19. 34. The process that breaks seed dormancy via chilling
Down
  1. 1. A cell found in plant ovules that release chemicals to guide the pollen toward the egg for fertilization
  2. 3. The photoreceptor that is sensitive (photo-reversibly) to red and far-red light, it regulates shade avoidance response, seed germination, and seedling de-etiolation
  3. 5. The plant hormone with an adenine base. It plays a role in (inhibiting) apical dominance, shoot growth, and regulate root growth in response to available nutrients.
  4. 8. The precursor to GA, ABA, and one of the precursors to Cytokinin
  5. 9. The tissue that connects the developing embryo to the endosperm
  6. 11. The plant hormone that is comprised of a non-aromatic ring and a carboxyl group. It plays a role in (inhibiting) seed germination, seed maturation, dehydration response in roots, and leaf senescence
  7. 12. A class of light sensitive biomolecules that are composed of proteins and chromophores.
  8. 14. The photoreceptor that is sensitive(photo-irreversibly) to blue light and regulates seedling de-etiolation, stomata opening, chloroplast movement, and phototropism.
  9. 16. A procedure that determines a chemical's effect over a variety of concentrations
  10. 17. The leaves of seedlings
  11. 19. The process that breaks seed dormancy via damaging the seed coat
  12. 22. The organization of leaf arrangement on a plant
  13. 23. The gaseous plant hormone that plays a role in fruit ripening, triple response in seedlings, and senescence.
  14. 25. A protective layer on the tips of roots
  15. 26. The plant hormone that is comprised of an aromatic ring and a carboxyl group.It travels through the plant via polar transport caused by the distribution of efflux and influx transporters on the basal and apical sides of the cell. It plays a role in many plant processes including: phototropism, (promoting) apical dominance, gravitropism, and root growth.
  16. 28. A plastid full of starch and aids in gravitropism in roots
  17. 29. The side of the leaf that is closest to the SAM (Shoot Apical Meristem)
