It is the process of the transfer of pollen from the male reproductive organ (the anther or male cone) of one plant to the female reproductive organ (the stigma or female cone) of another plant.
It is the method of fertilisation in unisexual plants.
It is dependent on agents of pollination that help carry the pollen grains to the stigma.
Cross-pollinating flowers include maple trees, daffodils, apples, and common grasses.
