Across
  1. 3. the ascending axis of the plant; normally above the ground; serves to support leaves, fruit, flowers, transport water, etc.
  2. 5. the primary phloem that develops first during primary growth.
  3. 6. A membranous structure part of the shoot apical meristem that covers or lines the growing tissue (corpus).
  4. 10. primordia, Groups of cells that will form into new leaves.
  5. 12. A pith with vascular tissue (xylem and phloem) forming a cylinder around it; Common in ferns.
  6. 13. the arrangement where protoxylem is inside and metaxylem is outside,
  7. 15. The regions of plants capable of division and growth.
  8. 18. When the protoxylem and protophloem is torn during elongation, causing a gap to form.
  9. 21. A horizonal underground plant stem capable of producing the shoot and root systems of a new plant.
  10. 24. The portion of a stem between two successive leaves or leaf pairs.
  11. 26. the arrangement in which the protoxylem is outside and metaxylem is inside.
  12. 27. Thickened, underground, upright stem modified for storage.
  13. 29. growth, an increase in thickness of the plant; only occurs when the plant has stopped growing.
  14. 30. The primary xylem that develops first during primary growth.
  15. 31. Multiple small vascular bundles scattered throughout the stem with no patterns; No distinguished pith.
  16. 32. Flattened photosynthetic stems.
Down
  1. 1. A region of the plant that contains an axillary bud, internode and a leaf; Is also called a module.
  2. 2. A tissue in the stems of vascular plants that stores and transports nutrients; Also called the medulla.
  3. 3. The part of the plant above the ground.
  4. 4. Enlarged, short, fleshy underground stems modified for storage.
  5. 7. The central vascular cylinder inside of the cortex of roots and stems of vascular plants.
  6. 8. apical meristem, Region of cells capable of division and growth in the root and shoot tips of the plant; Consists of tunica and corpus layers.
  7. 9. A non-medullated stele comprised of a central core of xylem surrounded by a cluster if phloem.
  8. 11. the later-formed part of the primary phloem that consists of mature phloem elements and its differentiated mainly after elongation of the axis has stopped.
  9. 14. the later-formed part of the primary xylem that differentiates after growth stops and is distinguished typically by border tracheids and vessels with pitted or reticulate walls.
  10. 16. A downward growing leafless stem which produces roots.
  11. 17. Modified stem designed for water storage, large thin-walled parenchyma cells.
  12. 19. the dividing cells of the shoot apical meristem responsible for growth, is covered by the tunica.
  13. 20. Modified stems designed for defense; Originating from the axillary bud.
  14. 22. growth, the rapid dividing of cells; primarily in the apical meristems of plants; located at the tips of roots and stems.
  15. 23. Modified stems designed for climbing.
  16. 25. primordia, the little buds at the end of stems; from which flowers develop.
  17. 26. Multiple small vascular bundles arranged to form a ring around the central pith; Common in dicotyledonous plants.
  18. 28. apex, The tip of the stem; which contains meristematic cells and the region of growth.
