What attracts an insect to a flower

Which part attracts insects to the flower?

Plants also use smell to attract an insect to their flowers. Some flowers like this cornflower are brightly coloured to attract insects.

Plants also produce scents to attract insects, probably as a way to advertise that food—nectar and pollen—is available. As the insect is drinking nectar or gathering pollen, it moves around in a flower and pollen grains, which sit atop long thin stalks in the flower's center, collect on its legs or underside.
