3.3b wind pollination

- the anther to the stigma is through air, carried by the wind
- light weight pollen grains are designed to float through the wind
- the anthers are exposed to the wind
- stigmas will have a large surface area- feather like structures to catch the pollen grains
- no colours, no scents, no nectories because there is no need to attract the insects

3.3a insect pollination

- the pollen gets transferred from the anther to the stigma
- pollen contains the male nuclei, this takes place by insects
- when one plant goes to another plant this is called cross pollination
- somethings that attract the insect to the flower are the colour of the petals and scents
- the value of the flower to the insect is the food and the pollen
- the anther and the filament form the stamen
