Down
  1. 1. A gibberellin associated with stem elongation
  2. 2. nondirectional responses to stimuli, often involving changes in turgor pressure
  3. 3. Directional growth in response to touch
  4. 6. A period of growth inactivity in seeds, buds, bulbs, and other plant organs even when environmental conditions normally required for growth are met
