Across
- 7. direction of growth determined by direction of gravity
- 8. IAA causes this in shoots and inhibits in roots
- 9. can detect change
- 10. a detectable change
- 11. growth response
- 13. direction of growth determined by direction of light
- 15. direction of movement determined by direction of chemical
- 17. result of detecting change
- 19. brings about response, usually a muscle or gland
Down
- 1. roots grow towards for anchoring
- 2. movement in random directions, with varying speed and frequency
- 3. roots grow towards for metabolic processes
- 4. movement in a specific direction
- 5. controls response
- 6. shoots grow towards
- 12. towards stimulus
- 14. plant growth factor
- 16. away from stimulus
- 18. speed and frequency of movement determined by presence of light
