Question

Why are rose flowers brightly-coloured and produce nectar?​

Answer 1

Answer:

Rose and other flowers are brightly colored and produce nectar (to attract the Pollinators) to aid pollination

Answer 2

In order to attract insects, insect-pollinated flowers are often brightly coloured, have scent and nectar, so the insect comes into the flower and collects or receives the pollen. The anthers of insect-pollinated flowers produce large pollen grains with a rough surface.
