  1. 1. the action of breathing.
  2. 7. a concentric layer of wood, shell, or bone developed during an annual or other regular period of growth.
  3. 8. a compact growth on a plant that develops into a leaf, flower, or shoot.
  4. 9. the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water
  5. 11. the part of a plant which attaches it to the ground or to a support, typically underground, conveying water and nourishment to the rest of the plant via numerous branches and fibers.
  6. 13. the main woody stem of a tree as distinct from its branches and roots.
  7. 14. tree or shrub that does not shed its leaves anually
  8. 15. cellular plant tissue from which phloem, xylem, or cork grows by division, resulting (in woody plants) in secondary thickening.
  9. 18. (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place.
  10. 20. the vascular tissue in plants that conducts water and dissolved nutrients upward from the root and also helps to form the woody element in the stem.
  11. 21. the soft outer layers of recently formed wood between the heartwood and the bark
  12. 22. the vascular tissue in plants that conducts sugars and other metabolic products downward from the leaves.
  13. 23. Orange pigment that colors pumpkins and leaves in fall
Down
  1. 2. the exhalation of water vapor through the stomata
  2. 3. the dense inner part of a tree trunk, yielding the hardest timber.
  3. 4. a region of plant tissue, found chiefly at the growing tips of roots and shoots and in the cambium, consisting of actively dividing cells forming new tissue.
  4. 5. uppermost part of any tree
  5. 6. (of a tree or shrub) shedding its leaves annually.
  6. 7. sugar that plants use as food
  7. 10. comprising organisms that share the same function in the food chain and the same nutritional relationship to the primary sources of energy.
  8. 12. any of the minute pores in the epidermis of the leaf or stem of a plant, forming a slit of variable width which allows movement of gases in and out of the intercellular spaces.
  9. 15. a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis.
  10. 16. a layer of parenchyma cells that is formed at the bases of fruits, flowers, and leaves before abscission
  11. 17. highest part of any plant or tree
  12. 19. a flattened structure of a higher plant, typically green and blade-like, that is attached to a stem directly or via a stalk. Leaves are the main organs of photosynthesis and transpiration.
