Answer:
angiosperms have flowers that attract organisms like insects, which aid in fertilization. The one evolutionary advantage of angiosperm over gymnosperm is the pressence of flowers. The pressence of flower makes it most successful among other plant group. The pressence of flower in the plant makes plant look more attractive and attracts insects for pollination. This property allows better transportation of flower.The more the insects are attracted towards the plant the transportation of seed will be more. Angiosperms contain both seeds and flowers, while gymnosperms only contain seeds.
