flower which collects pollen grains

18. Ovary – the female part of a flower, which
had the female sex cells called ovules

19. A process in which pollen grains from anther is
transferred to the stigma is called pollination.

20. Pollen is transferred by
• wind
• Water
• insects

The pollen grains reach to the eggs and combine with them. It is called
fertilization. The process after pollination is called fertilization. Then,
