3.3b Wind Pollination
- Wind pollination = the transfer of pollen from the anther to the stigma through air carried by the wind
- adaptation:
- light weight pollen grains (e.g. wing feature)
- anthers will hang clear from flower structure = sticking out so that they are exposed to the wind
- stigmas will be exposed, have a large surface area (feather-like structure) to catch the pollen grains as they pass through air on the wind and caught onto the stigma structure.
- no colour is needed to attract the insects, no scent, no nectaries
