What feature of the corn cob demonstrates wind pollination?

Step-by-step solution

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 –
