Explanation:
Detailed explanation-1: -Angiosperms evolved during the late Cretaceous Period, about 125-100 million years ago. Angiosperms have developed flowers and fruit as ways to attract pollinators and protect their seeds, respectively. Flowers have a wide array of colors, shapes, and smells, all of which are for the purpose of attracting pollinators.
Detailed explanation-2: -The success of angiosperms is due to two novel reproductive structures: flowers and fruit. The function of the flower is to ensure pollination. Flowers also provide protection for the ovule and developing embryo inside a receptacle. The function of the fruit is seed dispersal.
