Across
- 2. – The spongy center of exogenous plants. In the corn plant the pith fills the center cavity of the stalk and serves as a storehouse for moisture and food.
- 3. – Not woody, dying back to the ground each year, such as rhubarb and asparagus (applied to a plant or stems).
- 6. – The actively growing cells between the bark and the wood in a tree or shrub. They give rise to secondary xylem and phloem of dicotyledon stems.
- 9. – Plant whose seeds have two cotyledons or seed leaves, such as beans.
- 10. – Enlarged fleshy base of a stem, bulblike but solid, in which food accumulates.
- 12. – Study and matching of tree rings with the objective of dating events in the recent past.
- 13. – Stalk, trunk, branch of a plant. Can be vertical or horizontal.
- 15. – Thickened or swollen underground branch or stolon with numerous buds (eyes). Thickening occurs because of the accumulation of reserved food; e.g., Irish potato, Jerusalem artichoke.
- 17. – The place upon a stem that normally bears a leaf or whorl of leaves; the solid constriction in the culm of a grass; a knoblike enlargement.
- 18. – The portion of a stem or other structure between two nodes.
- 19. tissue – The fluid-conducting tissues of a plant including both xylem (water conducting) and phloem (food-conducting) tissues.
- 20. – Inner bark; the principle tissue concerned with the translocation of elaborated food produced in the leaves, or other areas, downward in the branches, stem, and roots.
- 21. – Plant having a single cotyledon or seed leaf, such as corn.
Down
- 1. – The undifferentiated plant tissue from which new cells are formed at the tip of a stem.
- 2. – Process by which green plants, using chlorophyll and the energy of sunlight, produce carbohydrates from water and carbon dioxide, release oxygen.
- 4. – The cellular layer of an organism; the outer skin.
- 5. – Elongated underground stems or branches of a plant which send off shoots above and roots below and are often tuber-shaped. These contain deposits of reserve food material and are used for vegetative propagation of plants.
- 7. – A protuberance containing miniature leaves or flowers, located terminally or laterally on a stem.
- 8. – Plant tissue capable of cell division and therefore responsible for growth.
- 11. – A lateral, aboveground shoot (stolon) of certain plants; e.g., strawberries, which roots forms young plants at some of the nodes, aiding in propagation.
- 14. – The “plumbing” system that conducts water and dissolved mineral up the stems from the roots.
- 15. – The transfer of the products of metabolism, etc., from one part of a plant to another.
- 16. – The subterranean bud of some plants, which have short stem overlapping, membrane-like leaf bases, as in onions and tulips. It stores food for reproduction and represents the inactive stage of the plant.
- 22. – The distension of the cell wall and protoplasmic layer of plants by fluids. It is essential to growth.
