Adaptations to Insect and Wind Pollination
Adaptations of Insect Pollinated Flowers
Attract Pollinators: brightly coloured petals, petal shape, food reward – pollen and/or nectar, fragrance – volatile chemicals released into the air.
Pollen Collection by Insect: sticky pollen – stays in contact with anther until insect arrives.
Pollen Capture By Flower: sticky stigmas so pollen from insect will transfer to them.
Adaptations of Wind Pollinated Flowers
Pollen Collection by Wind: smooth – easily removed from anther, small pollen easily transported by the wind.
Pollen Capture by Flower: stigmas large and feathery – greater surface area to intercept pollen, stigmas outside the flower
Massive Pollen Production: compensate for the excessive losses.
Note:
An adaptation is a feature (behaviour or modified structure) which fits the organism better to carry out a particular function.
Ideally name or describe the feature and then give its advantage.
The absence of a feature is not an adaptation
