(I)GCSE Topic 3.3 b) Wind Pollination

-Transfer of the pollen grain from the Anther to the Stigma through air, carried by the wind.

-Light weight pollen grains with a feature which allows them to move through the air more efficiently.

-Anthers will hang well clear over the basic flower structure so that they are exposed to the wind.

-Stigma have really large surface areas with a feature-like structure to catch the pollen grains as they pass through the air on the wind.

-No coulor, no scent, no nectaries needed to attract insects because they are wind pollinated.
