1 REPRODUCTION IN FLOWERING PLANTS

2 Let´s play!!! with some riddles…

3 CHANGE

4 Female reproductive organ
OVARY Female reproductive organ

5 t Spanish

6 FILAMENT It holds the anthern

7 P

8 SEPAL Small leaves under the flower

9 AL

10 PETAL

11 Contains pollen, the male reproductive cell
ANTHER Contains pollen, the male reproductive cell

12 RECEIVES THE POLLEN DURING FERTILIZATION
STIGMA RECEIVES THE POLLEN DURING FERTILIZATION

14 PARTS AND FUNCTIONS 1. Peduncle: Flower stalk.
2. Receptacle: flower stalk bearing the floral organs. 3. Sepal: Leaf-like structures at flower base, protects young flower bud. 4. Calyx: All the sepals together 5. Petal: Located in and above the sepals, often large and colorful, sometimes scented, sometimes producing nectar. Often serve to attract pollinators to the plant. 6. Corolla: All the petals together form the corolla. 7. Stamen: Male part of the flower, consisting of the anther and filament, makes pollen grains. 8. Filament: The stalk of the stamen which bears the anther. 9. Anther: The pollen bearing portion of a stamen. 10. Pollen  Grains containing the male gametes. 11. Carpel\Pistil: Female part of the flower. Consisting of the stigma, style and ovary. 12. Stigma: Often sticky top of carpel, serves as a receptive surface for pollen grains. 13. Style: The stalk of a carpel, between the stigma and the ovary, through which the pollen tube grows. 14. Ovary: Enlarged base of the carpel containing the ovule or ovules. The ovary matures to become a fruit. 15. Ovule: Located in the ovaries. Carries female gametes. Ovules become seeds on fertilization. .
