Across
- 2. Produced in tips of roots and shoots and promote growth by rapid elongation of cells, especially between stem and nodes. Also breaks dormancy of seeds and buds
- 4. length of day a plant needs more or less of in order to flower
- 9. layer of cells where leaves and fruit will fall from tree
- 10. Absorbs far-red light and is the biologically active form
- 11. regulation of activity by the length of daylight
- 13. plants that need long nights before they are able to flower
- 14. rapid reversible movements made in response to a change in stimulus. Not directed by stimulus. Not towards or away.
Down
- 1. plants that need short nights before they are able to flower
- 3. produced in tips of roots and promotes cell division, and growth in young fruit, slows aging of tissues
- 5. plants that flower independently of length of photoperiod
- 6. produced in tips of roots and shoots to promote elongation and differentiation of cells
- 7. occurs when a plant species is able to produce and release a chemical that prevents or inhibits the growth of the other plant species in the area around it.
- 8. growth responses made to stimuli with the response being directed by the stimulus. Can be positive and negative
- 12. Absorbs red light and is the inactive form
- 15. promotes formation of abscission zone
- 16. produced and accumulates in aging fruit to promote ripening
