Across
  1. 2. The leaf of a fern plant.
  2. 4. The region between nodes on a plant stem.
  3. 5. The point on a plant stem where leaves are produced.
  4. 7. In plants, the tissue that transports water and nutrients throughout the plant.
  5. 10. The diploid stage in the alternation of generations life cycle of plants during which spores are produced.
  6. 15. A structure within a plant seed that nourishes the developing embryo and may, upon germination of the seed, become the seedling's first leaves.
  7. 16. The leaflike structure that protects a flower bud during formation and supports the flower after blooming.
  8. 18. Any plant lacking tissues that can transport water.
  9. 20. A structure in a plant ovary that contains the egg cell and will mature into a seed.
  10. 22. A plant that produces flowers and fruits.
  11. 23. In plants, the type of vascular tissue that transports water and dissolved minerals from the roots to the rest of the plant.
  12. 25. A ripened plant ovary that contains seeds.
  13. 26. In woody plants, a thick, tough layer of dead epidermal cells that support the weight of the plant.
  14. 30. A root system consisting of many small roots that come directly from a stem.
  15. 32. Any flowering plant whose embryo has one cotyledon.
  16. 36. Any flowering plant whose embryo has two cotyledons.
  17. 38. The stalk that connects a flower to the rest of the plant.
  18. 39. The haploid stage in the alternation of generations life cycle of plants during which gametes are produced.
  19. 41. Undifferentiated cells found in the fast-growing parts of plants, such as root tips and new leaves.
  20. 43. In plants, the outer layer of cells that usually lack chlorophyll and serve for protection, including the secretion of the cuticle.
  21. 47. cell A modified epidermal cell that opens and closes stomata in the leaves of plants.
  22. 48. A plant having tissues capable of transporting water.
Down
  1. 1. A plant reproductive strategy that includes alternating spore-forming and gamete-forming stages.
  2. 3. The waxy protective coating secreted by a plant's epidermal cells on the surface of plant stems, leaves, and fruits.
  3. 6. A root system consisting of a large, main root (the taproot), from which smaller roots branch.
  4. 8. An area of porous tissue in the surface of a woody plant stem that allows for gas exchange with the environment.
  5. 9. In plants, the fertilization of both the egg cell and the polar bodies, which later form the endosperm.
  6. 11. The beginning of growth by a seed, spore, bud, or other structure after a period of dormancy.
  7. 12. A plant that produces unenclosed seeds, usually in cones.
  8. 13. The thickened top portion of a pedicel that supports the actual parts of a flower.
  9. 14. A visible ring caused by yearly growth in the vascular cambium and seen in a cross-section of a woody stem.
  10. 17. Any of the tissues that do not consist of dermal nor vascular tissue.
  11. 19. A layer of meristematic cells that replace the epidermis in woody plant stems.
  12. 21. A layer of meristematic cells located between the xylem and phloem in the woody stems of plants.
  13. 24. The stored food inside a plant seed.
  14. 27. A nonvascular plant including mosses, hornworts, and liverworts.
  15. 28. A structure on the underside of a fern frond that houses and protects the fern's sporangia.
  16. 29. The spongy ground tissue located in the center of a plant stem.
  17. 31. A small opening in the undersides of leaves that regulates gas exchange.
  18. 33. The female reproductive structure of a flower.
  19. 34. Any of the tissues that form the outer layer of a plant or other organism.
  20. 35. The small stalk that connects a leaf to the stem of a plant.
  21. 37. The male reproductive structure of a flower; produces pollen.
  22. 40. The type of vascular tissue in plants that transports food from the leaves to the rest of the plant.
  23. 42. The primary structural compound in plant cell walls, composed of long chains of glucose molecules.
  24. 44. The broad part of a plant leaf.
  25. 45. A flower structure located just inside the sepals and often large, conspicuous, and scented.
  26. 46. An undeveloped shoot located at a node on a plant stem.
