Across
  1. 2. / flap of tissue located at the base of a petiole, usually occurs in pairs
  2. 5. / includes stem, leaves and roots
  3. 7. / flattened photosynthetic surface of a leaf
  4. 8. / includes flowers, fruits, and seeds
  5. 9. / horizontal underground stem
  6. 11. / plant organ that supports leaves, may store food
  7. 12. / above-ground portions of the plant
  8. 15. / site where leaves are attached to stem
  9. 17. / sperm from the pollen unites with an egg present in the ovary
  10. 18. / leaf blade that attaches directly to stem; lack of a petiole
  11. 19. / portion of a grass leaf that wraps around the stem
Down
  1. 1. / meristematic tissue in roots that differentiates to form lateral roots and stems
  2. 2. / unbranched, elongated inflorescence
  3. 3. / the flowering part of a plant; a flower cluster
  4. 4. / meristematic tissue located in the leaf axils that produces flowers or lateral branches
  5. 6. / underground stem modified for food storage
  6. 8. / primary organ for water and nutrient uptake, may store food
  7. 10. / stem tissue in-between nodes
  8. 13. / pollen is delivered from the stamen to the pistil
  9. 14. / stem-like structure that attaches leaf blade to stem
  10. 16. / primary organ for conducting photosynthesis and exchanging gases
  11. 20. / a dense cluster of sessile flowers; inflorescence of the Asteraceae
