Question

In a flower which opens & exposes the anthers & stigma, which pollination is rare & which is common?​

Answer 1

Answer:

In a normal flower which opens and exposes the anthers and the stigma, complete autogamy is rather rare. Autogamy in such flowers requires synchrony in pollen release and stigma receptivity and also, the anthers and the stigma should lie close to each other so that self-pollination can occur.
