Flowers are morphological and embryological marvels and the sites of sexual reproduction. Inflorescences are formed which bear the floral buds and then the flowers. In the flower the male and female reproductive structures, the androecium and the gynoecium differentiate and develop.
Pollen grains once shed have to land on stigma before they lose viability if they have to bring about fertilization. The period for which pollen grains remain viable is highly variable and to some extent depends on the prevailing temperature and humidity. In some cereals such as rice and wheat pollen grains lose viability within 30 minutes of their release.
