Across
  1. 5. flower organ that receives pollen during fertilization; a female reproductive organ of the flower
  2. 6. “female” part of the flower; it includes the stigma, style, and ovary
  3. 9. one of two female reproductive organs that produces eggs and secretes the hormone estrogen
  4. 10. animal such as an insect or bat that picks up pollen on its body and carries it to another plant of the same species for pollination
  5. 12. flower organ that produces pollen; a male reproductive organ of the flower
  6. 13. process of breaking down food into nutrients that can be absorbed by the blood; includes mechanical digestion and chemical digestion
  7. 15. taxon below the kingdom in biological classification that consists of one or more classes
  8. 16. outer parts of flowers that are usually brightly colored to attract animal pollinators
  9. 17. the female reproductive structure of a flower which is part of the carpel or pistil; supports the stigma and connects it to the ovary
  10. 18. all of the sepals together, or the outside of the flower
  11. 19. stalk that holds up the anther
  12. 20. tiny grains that bear the male gametes of seed plants and transfer sperm to female reproductive structures
  13. 23. union of two gametes that produces a diploid zygote
  14. 24. fertilization in plants in which pollen is transferred to female gametes in an ovary of the same plant or a different plant of the same species
Down
  1. 1. structure in angiosperms consisting of male and female reproductive structures that attracts animal pollinators
  2. 2. haploid generation in the life cycle of a plant that results from asexual reproduction with spores and that produces gametes for sexual reproduction
  3. 3. structure in many flowering plants, also known as angiosperms, that develops from the ovary and contains seeds
  4. 4. part of a flower that helps protect it while it is still in the bud (before it opens)
  5. 5. male reproductive structure of a flower that consists of a stalk-like filament and a pollen-producing anther
  6. 7. bipedal, endothermic vertebrate that lays amniotic eggs and has wings and feathers
  7. 8. a type of reproduction in angiosperms where pollen from one flower travels to a stigma of a flower on another plant
  8. 11. part of the ovary that is the female gametophyte; becomes the seed after fertilization
  9. 12. multicellular, heterotrophic eukaryote with specialized cells that lack cell walls; member of the animal kingdom
  10. 14. arthropod in Class Insecta that has three body segments, six jointed legs, and multiple head appendages
  11. 21. structure produced by a seed plant that contains an embryo and food supply enclosed within a tough coat
  12. 22. petals of a flower collectively
