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.
