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