3.3b Describe the structures of a wind-pollinated flower and explain how it is adapted for pollination
Wind-pollinated flower
Once again, pollen needs to be transferred from the anther to stigma, but this time by wind (air).
Adaptations:
- Pollen grains are lightweight with some kind of wing features so that they can move throug the air more efficiently.
- Anthers will be exposed to the wind.
- Stigma has a large surface area, featherlike structure to catch the pollen grains as they pass through the air
- The petals have no colour in petals, no scent and no nectarine because there is no need to attract insects. This is a waste of energy for grass.
Excellent notes for 3.3a and 3.3b you will be able to get some real images in the lab
