AGENTS OF POLLINATION

Pollination by insects pollination by wind. Others e.g. birds, water, small mammals

Discuss in groups the topics above.

Room 1: Pollination by Insects.

Room 2: pollination by wind.

Room 3: pollination by other animals.

GROUP PRESENTATIONS

Each group to present their findings.

POLLINATION BY INSECTS

These flowers usually have brightly coloured, scented petals.

Some flowers make Nectar. Nectar is a sweet liquid. Insects visit the flowers to feed on the nectar. They are covered in pollen and carry the pollen to the stigma of the same flower or another flower.

POLLINATION BY WIND

Flowers pollinated by wind are not brightly coloured and do not have petals or scents. Wind pollinated flowers make lots of pollen. Pollen blows in the wind from the stamens to the stigma of other flowers.
