Give reasons for the following.

Flowers pollinated by insects are sweetly scented.

Scent:

1. Scent can also attract insects and birds which then carry the pollens.
2. The sweet scent is very alluring for the insects and hence we often observe a lot of insects on the flowers that smell sweet.
3. The insects come in search of nectar and in return they carry the pollen grains that get stuck with their bodies.
