In simple words, pollination is the reproduction process in plants. The male parts, called stamens, are long filaments; Generally these animals feed on nectar in the flower. Some—e.g., date palms (Phoenix dactylifera) and willows (Salix species)—have become dioecious; that is, some plants produce only "male" (staminate) flowers, with the rest producing only "female" (pistillate or ovule-producing) ones. Such flowers are called Ornithophilous.Thus, this option is incorrect. In flowering plants, pollination refers to transferring pollen grains from the male anther of a flower to the female stigma.
