Flowers pollinated by insects are large and brightly coloured. Give reason.

Pollination by insects:

1. The transfer of pollen grains from the anther to the stigma of the same or different flower is called pollination.
2. There are pollinating agents which are useful for pollination.
3. Insects, wind, birds and animals are examples of pollinating agents.
4. Flowers produce sweet smell and brightly coloured petals which attracts more insects to pollinate.
5. Sweet scents are used to attract insects and birds like humming birds and small bats.
