Through the movement of wind, pollen is transferred from the male part of the plant to another plant's female part.
In order for the pollen to be carried in the wind, it is made to be lightweight and has winglike features to help move effectively through air.
Also, the anthers will hang well clear of any flower structures so that they are exposed to the wind.
The stigma will have a large surface area, featherlike structure to catch the pollen grains as they pass through the wind.
The flower has no scent, no color or nectaries because it is a waster of energy as these features are not needed for wind pollination.
