BOTANY

Detailed explanation-1: -Effective pollination involves the transfer of pollen from the anthers to a stigma of the same species and subsequent germination and growth of the pollen tube to the micropyle of the ovule . Pollen transfer is effected by wind, water, and animals, primarily insects and birds.

Detailed explanation-2: -Pollination is simply the transfer of pollen grains from an anther to a stigma.

Detailed explanation-3: -In angiosperms, pollination is defined as the placement or transfer of pollen from the anther to the stigma of the same flower or another flower.

Detailed explanation-4: -Wind pollination has evolved at least 65 times from animal-pollinated ancestors, and approx. 10 % of angiosperm species rely on wind pollination (Linder, 1998; Ackerman, 2000).
