Question

Many flowers have bright patterns of coloration that directly surround the reproductive structures. How might this type of coloration be advantageous to the plant?

Answer 1

In flowering plants, reproductive structures are surrounded by sepals and petals. These are modified leaves which protect the reproductive parts.

Sepals are generally green in colour and collectively form calyx to support the petals.

Petals collectively form corolla; these are either white or brightly coloured.

(Flowers getting pollinated at night are generally white in colour.)

Coloured petals attract pollinators (which are mostly insects). Such pollinators are active during the day and must be endowed with colour vision.

Pollination is important for production of seeds and propagation.
