Across
  1. 5. These of leaves can be simple or compound.
  2. 7. Structure of _____: upper & lower epidermis & mesophyll (palisade & spongy)
  3. 10. Stems with both primary & secondary tissues, no vascular tissue with 3 areas (wood, bark, pith)
  4. 12. Plant growth toward/away from a one direction stimulus
  5. 13. Biological rhythms with a 24-hr cycle
  6. 14. Most abundant cells found in ALL organs of plants within ground tissue
  7. 17. Hormone promotes root & fruit GROWTH & prevents leaf & fruit loss (positive phototropism)
  8. 18. Hormone that is a gas where abscission & fruit ripening occur (increase enzymes to soften fruits & produce flavor/smell)
  9. 20. Movement in response to LIGHT
  10. 23. Hormones involving STEM ELONGATION to break dormancy of buds & seeds
  11. 26. Mature, nonwoody stems exhibiting only primary growth
  12. 27. Roots, stems, & leaves feature are what type of organs?
  13. 28. Meristems that form at stem/root tips, increasing tissue length & produce 3 tissue types.
Down
  1. 1. (2 words) Hormone produced by any "green tissue", STRESS hormone that maintains seed/bud dormancy, stomata closure, & abscission (dropping of leaves, fruits, flowers)
  2. 2. Cells with thicker walls & flexible support for immature plant regions within ground tissue.
  3. 3. Tissue that forms MOST of the plant, having Parenchyma, Collenchyma, & Sclerenchyma cells
  4. 4. Plants that live for 3 or more seasons, making vegetative structures for long survival
  5. 6. (2 words) Contains a shoot tip protected by bud scales of woody twigs
  6. 8. Chemical signals that coordinate cell responses, enable plant communication to react to environmental stimuli
  7. 9. Hormones that promote cell division & organ formation & low levels cause color change of leaves & die
  8. 11. Movement in response to TOUCH
  9. 15. First cells that form when plant embryo develops
  10. 16. Movements that do not involve growth & are not dependent on stimulus direction
  11. 18. Tissue that forms a plant's outer covering containing an epidermis
  12. 19. Tropism of growth TOWARD the stimulus
  13. 21. Tropism of growth AWAY from the stimulus
  14. 22. Plants that live for one growing season, have enough vegetative structures support
  15. 24. Movement in response to GRAVITY
  16. 25. Cells with lignin walls that support mature plant areas within ground tissue.
