Across
  1. 5. Union of an egg and sperm to produce a seed or fertilized egg.
  2. 8. Flower that lacks either stamens or pistils.
  3. 11. Collectively, all of the petals of the flower.
  4. 12. Substance necessary for the functioning of an organism.
  5. 13. Stalk, trunk, branch of a plant. Can be vertical or horizontal.
  6. 14. Designating a flower that has a pistil or pistils but lacks stamens; an imperfect flower.
  7. 16. Sprouting of a seed and beginning of plant growth.
  8. 17. Group of sepals on a flower.
  9. 18. The receptive surface of the female organ of a flower that receives the pollen.
  10. 19. A flower containing sepals, petals, stamens, and at least one pistil.
  11. 20. A flower with both stamens and a pistil or pistils.
  12. 24. A chemical process that takes place in living cells whereby food (fats, carbohydrates, and proteins) is “burned” (oxidized) to release energy and waste products, mainly carbon dioxide and water. Living things use the energy produced through respiration to derive vital life processes, such as growth and reproduction.
  13. 26. A white, granular, organic chemical that is produced by all green plants.
  14. 27. tube Tube formed following the germination of a pollen grain, when the grain resides on the stigma of a flower. The tube carries the male gametes to the ovule.
  15. 31. The body that, after fertilization, becomes the seed; the egg-containing unit of the ovary.
  16. 34. Percentage of seeds that sprout and begin to grow.
  17. 35. The embryo of a plant; also kernel of corn, wheat, etc., which botanically are seed-like fruits, including the ovary wall.
  18. 36. In the pistil of a flower, the part between the ovary and the stigma.
  19. 37. The portion of the pistil or carpel of a flower that contains one or more ovules.
Down
  1. 1. Small, green, leaf-life structure found at the base of a flower.
  2. 2. A flower that lacks one or more of the four organs: sepals, petals, stamens, or pistils.
  3. 3. Mature ovary, seed.
  4. 4. The uniting of pollen and ovule cells.
  5. 5. Designating a flower that has stamens but no pistil and hence is imperfect.
  6. 6. A substance present in all green plants; it evidences itself as the green coloring in leaves. Chlorophyll transforms light energy from the sun into chemical energy to manufacture plant food from carbon dioxide, water, and essential soil minerals. This process is called photosynthesis.
  7. 7. The transfer of the pollen from the anther to the stigma of a flower, the first step in producing fruit or seed.
  8. 9. A division of a flower inside the calyx; a unit of the corolla, consisting of petioles, which usuallysurrounds the pistils and stamens.
  9. 10. The saclike part of the stamen on seed-producing plants that develops and contains the pollen.
  10. 15. The part of the stamen of a flower below the anther and supports it.
  11. 18. The organ of a flower that bears the pollen (microspores) consisting of the stalk (filament) and the anther.
  12. 21. The lower portion of a plant bearing neither leaves nor reproductive organs that mostly develops underground and anchors the plant in the soil. It bears root hairs, which absorb water and mineral nutrients.
  13. 22. The reproductive structure of a seed-bearing plant consists of the male and/or female organs surrounded by one or two series of outer coverings.
  14. 23. The male element that carries the spores in the fertilization of the egg nucleus in the ovule of a flower. The pollen is borne by the anthers and is usually a yellowish, dust-like mass of separate grains.
  15. 25. Any organism in its earliest stages of development.
  16. 28. The female element of a flower; composed of stigma, style, and ovary.
  17. 29. A simple sugar that is an important energy source in living organisms and is a component of many carbohydrates.
  18. 30. The making of a new plant or animal.
  19. 32. Any herbaceous plant whose fruit, seeds, roots, tubers, bulbs, stems, leaves, or flower parts are used as food.
  20. 33. A flattened outgrowth from a plant stem, varying in size and shape, usually green, concerned primarily with the manufacture of carbohydrates by photosynthesis.
