Detailed explanation-1: -Pollination is simply the transfer of pollen grains from an anther to a stigma. Fertilization occurs much later when the pollen grains germinate on the stigma and send down a pollen tube which releases the sex cells to fertilize the ovules.
Detailed explanation-2: -Self-pollination is referred to as the primary type of pollination, which occurs by transferring the pollen grains directly from the anther into the stigma of the same flower.
Detailed explanation-3: -In all wind-pollinated flowers, the mature stigma is found rough and sticky.
Detailed explanation-4: -The pollen grains are light and non-sticky so that they can easily be carried by air currents. The flowers have no petals so that stamens remain well-exposed which helps in an easy dispersal of pollen by wind currents. Flowers have a large feathery stigma to easily trap the airborne pollen grains.
