3.3b

objective 3.3b: describe the structures of an insect pollinated and a wind pollinated flower and explain how each is adapted for pollination.



wind pollination= transfer of pollen grain from anther of one plant to stigma of the other through the air carried by the wind

the adaptations a wind pollinated plant would have would be:
lightweight pollen grain, maybe with wings so to catch the wind better.

the anther will hang well clear of the main flower structure so they are exposed to the wind.

the stigma will have a large surface area maybe in a feather-like structure to catch the pollen grains as they pass through the air. the stigma will also be well clear of the main flower structure and be exposted.

grass is an example of a wind pollinated plant

grass has no colour, scent, or nectaries as there is no need to attract insects as it is wind pollinated. the features if an insect pollinated plant would be a waste of energy.
