Explanation:
1. A bisexual flower consists of both the male part (androecium) and the female part (gynoecium).
2. Pollination is the process of transfer of pollen grains from anther to stigma.
3. Fertilization can be defined as the fusion of the female reproductive nucleus with the male reproductive nucleus.
4. Tube nucleus and generative nucleus are the two nuclei at the end of the pollen tube.
5. 2 male nuclei arise when the generative nucleus divides.
6. Embryo sac is located inside the ovule of the flower.
7. One of the nuclei of the pollen tube and the secondary nucleus of the ovum grow into the endosperm.
8. Male reproductive parts of the flower is called Androecium
9. Gynoecium is also called the pistil.
10. Geitonogamy is a form of autogamy that requires pollinators.
11. Banana is produced by parthenocarpy.
12. Apomixis is the process of formation of seeds without fertilization in flowering plants.
13. Autogamy and geitonogamy is prevented in dioecious plants.
14. Zygote is formed by the fusion of male gamete and egg nucleus.
15. Oxygen, water and suitable temperature are required by seeds for germination.
