3.3b - Wind pollination

Anther => Stigma
Air - wind

Adaptations
1. Light pollen grains - with wing feature (moving through air more efficiently)

2. Anthers hanging away from basic flower structure - exposed to wind

3. Stigma

- large surface area

- far away from flower structure
- feather-like structure to catch pollen grains from the wind
- exposed to wind



Grass
- No colour in petals (no need to attract insects)
- No scent
- No nectaries
(Waste of energy for plant)
