3.3b Wind Pollination

Key Points:

1. Its the transfer of pollen grains from the anther to the stigma through air carried by the wind
2. An adaptation of the pollen is lightweight grains, probably with some kind of wing feature which allows them to move through the air more efficiently
3. The anthers will hang well clear of any basic flower structure so that they are exposed to the wind
4. Third feature is the stigmas, and again they have a large surface area, and a kind of feather like structure to catch the pollen grains as they pass through the air on the wind and will be caught onto the stigma structure
5. No colour in the petals, no scent in the grass, and also have no nectaries because this is a waste of energy, because they don't need to attract insects.
