Question

Why in some flowers stigma matures earlier than stamen?​

Answer 1

Answer:

By maturing the anther and stigma at different times, the flower is forced to fertilize or be fertilized by another. This is nature's way of preventing inbreeding and ensuring that the result will be vigorous progeny through cross-pollination.
