Detailed explanation-1: -Researchers believe flowers evolve their features over time to better attract birds, bees, and other pollinators. To lure hummingbirds, for example, certain flowers produce red and orange colors, while certain plant species produce bright colored petals or ultraviolet patterns to attract bees.

Detailed explanation-2: -The most common pigments in flowers come in the form of anthocyanins. These pigments range in color from white to red to blue to yellow to purple and even black and brown. A different kind of pigment class is made up of the carotenoids. Carotenoids are responsible for some yellows, oranges, and reds.

Detailed explanation-3: -AP1 and LFY activate floral homeotic genes13, which then act in a combinational fashion to specify the identities of four different types of floral organs (sepals, petals, stamens, and carpels).
