Petals in flower protects the plant’s reproduction parts. They also attract pollinators like bees, butterflies, moths to land on them and spread the pollen to other flowers.

In addition to Ilma’s comment – For insect-pollinated flowers, petals often have patterning in UV which the insects can see but the human eye cant, which basically attract the insects and tell them were to go. While wind-pollinated flowers often have small dull petals as they are not needed to attract insects.

One of my friends studied some special plants that didn’t have petals, in a crop called oilseed rape (you can’t fail to notice it, it is the really bright yellow flowers in April to June that fill whole fields, we use it to make vegetable oil for cooking with). They’re so bright because they reflect a lot of light, and he wanted to test whether not having the petals meant that sunlight reached further down into the crop instead of bouncing off the flowers. It did! That has the potential to increase the yield of seed.
