Presentation Transcript

  1. Sexual Reproduction • two parents • male gamete • female gamete • genetic variation

  2. pistil stamen petals receptacle sepals

  3. sepals Sepals • outermost appendage of a flower • protect the flower while it is developing and after the flower buds • usually green

  4. Petals • usually colorful • attract pollinators

  5. stamen Stamen • the male reproductive structure

  6. Stamen • the male reproductive structure • the long filament which bears the anther

  7. filament Filament • the stalk of the stamen

  8. anther Anther • the saclike structure that produces and stores pollen

  9. Pollen • the male gamete

  10. pistil Pistil • female reproductive part of a flower • consists of three main sections: ovary, style, and stigma

  11. ovary Ovary • contains the ovules, which are the female gametes • matures into the fruit that surrounds the seeds

  12. stigma

  13. Stigma • expanded tip of the carpel • receives the pollen stigma

  14. style Style • slender stalk • between stigma and ovary

  15. Gametes • male gamete  pollen • female  ovule

  16. pollination the process of transferring pollen from an anther to a stigma

  17. carpel

  18. gamete + gamete = zygote

  19. zygote  seed • seed  plant

  20. seed coat stored food

  21. pollen tube tube that grows from pollen on a stigma, down the style, and into the ovary of a flower

  22. ovule contains the female gamete

  23. fertilization the formation of a zygote from the union of two gametes

  24. fruit the ripened ovary of a flower

  25. Asexual Reproduction • the production of a new organism without the joining of gametes • reproduction that takes place by mitotic cell division

  26. prophase interphase metaphase anaphase telophase cytokinesis complete

  27. Asexual Reproduction • runners with plantlets • root sprouts • leaf cutting • stem cutting • root cutting
