Pollination by wind is more common amongst abiotic pollinations. Wind pollination also requires that the pollen grains are light and non-sticky so that they can be transported in wind currents. They often possess well-exposed stamens (so that the pollens are easily dispersed into wind currents,) and large often-feathery stigma to easily trap air-borne pollen grains. Wind-pollinated flowers often have a single ovule in each ovary and numerous flowers packed into an inflorescence; a familiar example is the corn cob – the ears you see are nothing but the stigma and style which wave in the wind to trap pollen grains. Wind-pollination is quite common in grasses.
NTA tests students on the specific structural and functional adaptations flowers develop for wind pollination. The core concept is that wind-pollinated flowers have light, non-sticky pollen, exposed stamens, and feathery stigmas to maximize pollen dispersal and capture. Students often mistake wind pollination for insect pollination by confusing which flowers have showy petals (insects) versus exposed reproductive structures (wind). The key to getting it right: remember that wind-pollinated flowers like grasses are typically inconspicuous with exposed stamens and styles that wave in air, single ovules per flower, and numerous flowers in compact inflorescences for efficient pollen release.
