  1. 2. A plant hormone that promotes cell division and the development of lateral buds.
  2. 3. A plant hormone that promotes cell elongation and lateral root development.
  3. 4. A plant pigment that regulates a plant's response to photoperiod changes.
  4. 7. The growth movement of a plant in response to gravity.
  5. 8. An organism that is genetically identical to its parent.
  6. 10. The fluid transported by xylem and phloem in a plant.
  7. 11. The pressure exerted by water in a full central vacuole upon the cytoplasm and cell membrane of a plant cell; maintains plant rigidity.
  8. 14. The rising of a fluid within a tube due to adhesion between the molecules of the fluid and the tube.
  9. 17. One of a group of plant hormones with a role in regulating many aspects of plant growth, mainly that of stem elongation and cell division in shoots and leaves.
  10. 18. A directionally dependent growth response of plants to external stimuli such as light, gravity, touch, and the presence of water.
  11. 19. Any form of asexual reproduction in a plant.
  12. 20. A chemical regulator produced in an endocrine gland and carried in blood to its target cell in order to produce a response.
  13. 21. A plant that requires a short period of darkness in order to flower.
  14. 22. The response of a plant to the duration and intensity of light exposure.
  15. 23. A plant hormone that acts as an inhibitor of other hormones and causes dormancy in buds and seeds.

  1. 1. Growth movement of a plant in response to touch, primarily found in climbing plants such as vines.
  2. 2. The currently accepted theory that explains the flow of water upward in the xylem of plants.
  3. 5. A plant hormone that regulates the ripening of fruit, opening of flowers, and shedding of leaves.
  4. 6. The best-supported theory for explaining the flow of sap in the phloem of a plant.
  5. 9. A plant that flowers independently of the photoperiod.
  6. 12. A plant that requires a long period of darkness in order to flower.
  7. 13. The release of water through the leaves of a plant.
  8. 15. The growth movement of plant roots in response to the presence of water.
  9. 16. Growth movement of a plant in response to light.
