Across
  1. 1. female part of the flower
  2. 3. the top of the carpel where pollen lands
  3. 6. the structure at the base of the flower which supports everything else
  4. 10. the seed leaves of a seed; sometimes they are a food store
  5. 11. the part of the flower which is often colourful to attract pollinators
  6. 13. reproductive organ of a plant
  7. 14. develops from the ovary after fertilisation to aid seed dispersal; often eaten by animals
  8. 16. involves the production of gametes by a male and a female and results in offspring that are genetically different from their parents
  9. 18. male part of the flower
  10. 21. the structure in the ovary which develops into a seed when fertilised
  11. 22. a group of plants that only have one cotyledon; use the endosperm as an energy store in seeds
  12. 24. part of the stamen that produces pollen
  13. 26. the part of the carpel which connects the stigma and ovary
  14. 28. results in genetically identical offspring; also known as vegetative propagation
  15. 30. the young plant that is developing in the seed; composed of the cotyledon, plumule and radicle
  16. 31. the fusion of the male and female gamete resulting in a zygote which develops into an embryo
Down
  1. 2. the part of the embryo that will become the root
  2. 4. the results of sexual reproduction in plants; can develop into a new plant
  3. 5. when an embryo in a seed starts to develop into a young plant; requires heat, warmth & oxygen
  4. 6. lateral stems develop and form a new plantlet; a form of asexual reproduction
  5. 7. the seed coat; develops from the ovule wall
  6. 8. the transfer of pollen from the anther of one flower to the stigma of another flower; can be by insects (or birds) or by wind
  7. 9. powdery grains released by anthers which contain the male gamete (sperm)
  8. 12. part of the stamen which connects the anther to the base of the flower
  9. 15. a group of plants with two cotyledons; use the cotyledons as an energy store in seeds
  10. 16. part of a plant which holds the leaves or flowers
  11. 17. underground structure where side buds develop into new plants; a form of asexual reproduction
  12. 19. main food store in the seed
  13. 20. the tube that grows down the style in a flower after pollination to deliver the male nucleus to the ovary
  14. 23. the base of the carpel which holds the ovules
  15. 25. the part of the embryo that will become the shoot
  16. 27. the outer part of the flower which is usually green and leaf-like
  17. 29. underground storage organ that can form buds from the potato “eyes” which can grow into a new potato plant; a form of asexual reproduction
