3.3b Wind Pollination

• The transferred of the pollen grain from the anther to the stigma through air carry by the wind.
• Pollen grains first adaptations is to have light weight, wings features which allowed to move through the air more efficently. Secondly we were expect to find the anther will hang well clear, anther will expose to the wimnd.
• Third feature which related to the stigma, we would expect the stigma has large surface area a kind of feather like structure to catch the pollen grain.
• They pass through the air on the wind wich will be caught on the stigma structure here.
• If we look at the image here f the grass no colour, no scent, no nectaries and no point of producing sugar which is the waste of energy for the grass which the wind that pollinated the plant and the adaptaions are light pollen grain, exposed anthers and exposed stigma.
