Across
  1. 2. -seedless vascular plants. vascular tissue hardened by lignin. mainly horsetail, club mosses, and ferns.
  2. 3. - plants with woody parts that grow year after year.
  3. 9. - a seed leaf that develops as part of the seed providing nutrients to the seedling and becomes the first leaf of the plant. may perform photosynthesis or whither from lack of nutrients.
  4. 12. - a fine dust containing the sperm of seed producing plants.
  5. 16. - swelling on the tip of the pedicel that holds the developing flower bud and then supports the flower.
  6. 19. - 2 sets of chromosomes, one from each parent.
  7. 20. - transfer of pollen grains from anther to carpel in flowering plants.
  8. 24. - 4 haploid cells following meiosis in an angiosperm encased in a thick protective wall.
  9. 27. - plants that live for 2 years.
  10. 29. - male reproductive organs of the flower. have long filaments serving as stalks to support the anther. produce pollen grains which contain sperm.
  11. 30. - (without vascular tissue). frequent in forests where the soil is cool and moist but can live in any moist shady area from tropical to polar. most recognizable are mosses. rely on osmosis for water.
  12. 31. - protective coating of an ovule.
  13. 32. - middle portion of the embryo that develops into the stem.
  14. 33. - covered in a sticky substance designed to catch pollen grains.
  15. 35. - green leaflike structures above the pedicel. enclose the bud of the flower to protect.
  16. 37. - the plant a stem is being grafted to.
  17. 38. - lower portion of the embryo that sprouts out of the seed.
  18. 40. - flowering plants enclosed seed surrounded in protective tissue.
  19. 41. - plants with a vascular tissue system of tube-shaped cells branching throughout a plant that transports materials between roots and shoots.
Down
  1. 1. - fruit with ovary wall connected to the seed. ex corn
  2. 4. - diploid generation.
  3. 5. - extension of the ovary designed to hold the stigma up where it can be exposed to pollen grains.
  4. 6. - haploid generation.
  5. 7. - top portion of the embryo from which the true leaves form.
  6. 8. - flowers made up of several individual flowers. ex sunflower is actually numerous tiny flowers that form in a single receptacle.
  7. 10. - embryo breaks through the seed wall.
  8. 11. - means naked seed because the seed is not enclosed in protective tissue. most common group evergreens or conifers.
  9. 13. - regions in each anther of a flowers stamen where diploid cells undergo meiosis to form haploid cells.
  10. 14. - a mature ovary that contains a seed or seeds.
  11. 15. - leaflike structures above the sepals. contain carotenoids and other pigments that provide color. epidermis often contains fragrant oils to attract pollinators.
  12. 17. - contains the eggs of the plant where the seeds develop.
  13. 18. - flowers with either stamens or carpels.
  14. 20. - flowers that have both reproductive organs.
  15. 21. - ovary forms a hard woody covering around a single seed. ex walnut and acorn
  16. 22. - contains pollen grains that contain haploid cells that function as plant sperm.
  17. 23. - contains the ovule where the embryo sac develops.
  18. 25. - female reproductive organ of the flower. (produces embryo sacs which contain the eggs.) composed of stigma, style and ovary.
  19. 26. - dry fruit ovary with a single chamber containing many seeds. such as bean and peanuts.
  20. 28. - cutting a stem from one plant and attaching it to another.
  21. 33. - an ovule with a protective coating encasing a mature plant embryo and a nutrient source.
  22. 34. - 1 set of chromosomes resulting from meiosis.
  23. 36. - the stem cut from a plant for grafting.
  24. 37. - fruit forming a long thin wing from the ovary wall. ex maple.
  25. 39. - dry fruit ovary with many champers each containing many seeds. ex poppy
  26. 40. - plants that only live for 1 year. grow, flower, produce seeds and die.
