  1. 8. The process by which cells derived from the same meristem become structurally and functionally specialised.
  2. 12. A plant growth regulator generally associated with growth inhibition, dormancy and responses to environmental stress.
  3. 14. The initial phase of the growth curve during which growth is slow.
  4. 19. The phase of a growth curve in which growth slows down and eventually becomes nearly constant.
  5. 20. The phase of rapid growth in a sigmoid growth curve.
  6. 21. The process by which living differentiated cells regain the capacity to divide under certain conditions.
  7. 23. A type of growth in which both daughter cells produced by division retain the ability to divide, resulting initially in exponential growth.
  8. 25. The rapid elongation of the internodes of certain plants before flowering.
  9. 26. An irreversible permanent increase in the size of an organ or its parts, or in the size of an individual cell.
  10. 27. A group of actively dividing cells that contributes to the growth of a plant.
  11. 28. A type of growth in which one daughter cell continues to divide while the other differentiates, resulting in a linear increase.
  12. 30. Growth resulting from the activity of apical meristems that increases the length of roots and shoots.
  13. 31. A meristem located along the sides of stems and roots that contributes to an increase in girth.

  1. 1. The phase of growth in which cells increase substantially in length.
  2. 2. Growth resulting from the activity of lateral meristems that increases the girth of plant organs.
  3. 3. A temporary state in which growth and development are suspended or greatly reduced.
  4. 4. The sum of growth and differentiation that occurs during the life cycle of a plant.
  5. 5. A meristem located between mature tissues, commonly at the bases of internodes or leaves in grasses.
  6. 6. A plant growth regulator that promotes cell division and can delay leaf senescence.
  7. 7. The type of cell division that increases the number of cells during plant growth.
  8. 9. The phase in which cells attain their final form and become specialised.
  9. 10. A gaseous plant growth regulator that promotes fruit ripening and is also involved in senescence and abscission.
  10. 11. The ageing process in plants that ultimately leads to the death of cells, tissues or organs.
  11. 13. The total growth of a plant organ or organism measured over a given period.
  12. 15. The process by which dedifferentiated cells become specialised again to perform specific functions.
  13. 16. A plant growth regulator that promotes cell growth, particularly cell elongation, and has many other effects on plant development.
  14. 17. A type of meristem located at the tips of roots and shoots and responsible for primary growth.
  15. 18. A type of growth measurement based on changes in size, mass, volume or cell number.
  16. 22. Growth expressed in relation to the initial size of the growing organ or organism.
  17. 23. A plant hormone that promotes growth in the stem, induces bolting in rosette plants and can promote seed germination.
  18. 24. The characteristic S-shaped curve obtained when growth is plotted against time.
  19. 29. The phenomenon in which the apical bud suppresses the growth of lateral buds.
