Question

Why do wind pollinated flowers have long and feathery stigmas?

Answer 1

Hint: Pollination by wind is called anemophily, and the flower should have a female part of enormous size, fluffy stigma and distending over the other botanical part for effective fertilization.

Complete answer:
Pollination is the transfer of pollen from a male part of a plant to a female part of a plant, later enabling fertilisation.
Wind fertilizing flowers might be little in measure and don't have any scent, nectar, or petals to affirm the fertilization; the female part might be stripped or enormous in size. The stigma is huge, padded, projecting outside to get the pollen grains and affirm the fertilization. Anther will deliver in huge numbers. The vast majority of the coniferous plants and 12% of the world's flowering plants are wind pollinated. Fluffy and uncovered stigmas present which have wind pollinated characters yet on the off chance that padded stigma is available inside the flower part which may not permit the wind pollination. It requires another sort of vector or medium to fertilize the attributes of the flower. In tight exserted stigma type, the highlights of flowers may not permit the wind pollination rather it requires other medium like water or different things like birds or bats which affirms the fertilization of such flowers. In the restricted embedded stigma sort of highlight, the flowers need insects which can go inside the flower and affirm the fertilization, since stigma is available as embedded in flowers and it can't be pollinated by the wind.

Note:
Wind pollinated flowers should show such kind highlights like enormous distending stigma, padded tacky stigma without petals, smell and nectar to affirm the fertilization and anther produce light and huge quantities of pollen grains which can travel significant distances with wind.
