-Transfer of the pollen grain for the anther (By air, carried through Wind) to the Stigma
- Adaptations:
1. Lightweight pollen grains with some kind of wing feature which allows them to move through the air efficiently
2. Anthers will hang well clear of any basic flower structure, exposed to the wind.
3. Stigma, large surface are, feather like structure to catch the pollen grains as they pass through the air on the wind.
- Grass, no colour in the petals and no scent to attract insects.
- Waste of energy to produce nectarines since it is a wind pollinated plant.

putting more energy into what?
ReplyDeleteMaking the parts of the plant easier to be picked up by the wind. i.e lightweight = easier to be picked up. They dont have to spend any effort attracting animals.
