    Variation in flower structure has broadly two purposes:-
    1. Enhance the survival value by ensuring cross-pollination. Darwin proved that if we took equal quantities of self-fertilized and cross-fertilized seed, a much greater percentage of cross-fertilized seed is fertile, and what ...

    Solution Summary

    Variation in flower structure enhance the survival value by ensuring cross-pollination. Coevolution on other hand, results in exquisite adaptations between flower and pollinator. These adaptations can minimize competition for nectar and pollen among pollinators and also can minimize competition among flowers for pollinators.
