Across
- 3. Inner bark; the principle tissue concerned with the translocation of elaborated food produced in the leaves, or other areas, downward in the branches, stems, and roots.
- 5. The actively growing cells between the bark and the wood in a tree or shrub. They give rise to secondary xylem and phloem of dicotyledonous stems.
- 7. The intake of water, gases, nutrients, or other substances by plants.
- 8. The outer layer or region of any organ.
- 10. Undeveloped or embryonic shoot and normally occurs in the axil of a leaf or at the tip of the stem.
- 13. A root system that is comprised of profusely branched roots with many lateral rootlets.
- 17. The development or growth of a cell, organ, or immature organism into a mature organism.
- 18. The distension of the cell wall and protoplasmic layer of plants by fluids. It is essential to growth.
- 20. Stalk, trunk, branch of a plant. It can be vertical or horizontal.
- 21. Any of a number of field and garden crops whose underground roots are used as food for people and animals, like turnips, beets, carrots, and sweet potatoes.
- 22. A flattened outgrowth from a plant stem, varying in size and shape, usually green, which is concerned primarily with the manufacture of carbohydrates by photosynthesis.
- 25. The primary descending root, usually conical, of a plant from which lateral branching roots may develop; e.g., as in carrots and alfalfa.
Down
- 1. A lateral branch of a primary or main root.
- 2. The fluid-conducting tissues of a plant including both xylem (water-conducting) and phloem (food-conducting) tissues.
- 4. A hair-like growth on an epidermal cell of the root. It absorbs water and mineral nutrients for the plant.
- 6. A thin, flexible sheet of vegetable or animal tissue; the thin protoplasmic tissue connecting, covering, or lining a structure, such as a cell of a plant or animal.
- 9. The “plumbing” system that conducts water and dissolved mineral up the stems from the roots.
- 11. The temporary or transient loss of turgidity in a plant, caused by a rate of transpiration in excess of the rate of absorption of water.
- 12. A plant that lives for two years and then dies.
- 14. The flow of a fluid through a semi-permeable membrane separating two solutions, which permits the passage of the solvent but not the dissolved substance. The liquid will flow from a weaker to a stronger solution, thus tending to equalize concentrations.
- 15. Swollen, or tightly drawn, said of a membrane or covering expanded by pressure from within; e.g., growing plants have turgid cells.
- 16. The main descending axis of a plant; the pole of the embryo opposite the shoot.
- 19. A plant that lives for more than two years.
- 23. The extreme tip of the root consisting of a group of cells that slough off and are replaced as the tip moves through the soil. It protects the growing region of the root.
- 24. The reproductive structure of a seed-bearing plant, consisting of the male and/or female organs that are surrounded by one or two series of outer coverings (calyx and corolla).
