  1. 3. ___________ Acid Function: inhibits cell growth, closing stomata. Produced in: Mature leaves, fruits; NOT involved in abscission of leaves.
  2. 6. Induces seed germination GA increases internode length, encourages flowering (regulate growth and development). Produced in Seeds, tips of roots and shoots.
  3. 8. are chemicals that regulate cell processes.
  4. 9. is the coordination of growth and differentiation, regulated by genes and the environment.
  5. 10. The _______________ determines which genes are active.
  6. 15. Lateral buds can be reactivated by ________________.
  7. 16. Auxins,Gibberellins, Cytokinins ________ plant growth.
  8. 17. Internal factors include position, hormones, ___________.
  9. 18. Agent _________ was a synthetic auxin used as defoliant in Vietnam War.

  1. 1. Abscisic Acid, Ethylene ______ plant growth.
  2. 2. Auxin/Cytokinin __________ often determines plant growth.
  3. 4. Promotes cell division and enlargement, and is produced in roots
  4. 5. Specialization of cells into different tissues and organs.
  5. 6. Irreversible increase in mass due to division and enlargement of cells.
  6. 7. Function: a ripening agent, leaf and flower abcission. Produced in: Leaves, stems, young fruits.
  7. 11. Differentiate ground tissue (parenchyma), vascular tissue (xylem/phloem), dermal tissue (root hairs).
  8. 12. ______________ are the units of heredity.
  9. 13. Function is to promote cell elongation (cell growth) and is produced in Apical Meristems, Buds, Young Leaves
  10. 14. ________________ dominance, Suppression of lateral (axillary) buds is controlled by auxin inhibitors.
