**[Questions]** 1. What is the function of the sepal? To protect the flower 2. What is the function of the petals? To attract insects for pollination 3. What is the function of the stamen? To produce the pollen grains in the anthers. 4. What is the function of the anther? To produce pollen 5. What is the function of the filament? To hold the anther in place 6. What is the function of the carpel? To produce the ovules. 7. What is the function of the stigma? Where the pollen lands after pollination. 8. What is the function of the style? The pollen travels down this. 9. Microspore mother cells divide by what to give a tetrad of haploid cells? Meiosis 10. What are the two haploid nuclei produced when the pollen grains divide by mitosis? A tube nucleus and a generative nucleus. 11. Define pollination. The transfer of pollen from the anther to the stigma of a flower of the same species. 12. Define self-pollination. Transfer of pollen from an anther to a stigma of the same plant. 13. Define cross-pollination. Transfer of pollen from the anther to the stigma of a different plant of the same species. 14. Name two methods of pollination. Insect and wind pollination. 15. Name two adaptions an insect-pollinated plant has Brightly-coloured petals, sticky pollen. 16. Name two adaptions a wind-pollinated plant has. Light, dry pollen and a long feathery stigma. 17. What is fertilisation? Fertilisation is the fusion of the male (n) and female (n) gametes to produce a zygote (2n) 18. Define dormancy. A period of little to no metabolic activity or growth. 19. Name an advantage of dormancy. Dormancy allows the embryo time to develop. 20. Name two methods of dispersal. Wind and animal dispersal. 21. Name an advantage of dispersal. New areas are colonised 22. What is germination? The re-growth of the embryo into a new plant following dormancy providing conditions are suitable. 23. Name two factors needed for germination to occur. Water, correct temperature.
