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