Stamens and pistils problem?

Question

why are stamens and pistils considered modified leaves?

Answer 1

Flowers are modified stems; flower parts are modified leaves; the stamens have evolved from more primitive microsporophylls and the pistils from megasporophylls.(See link1.)

Bisexual flower show four distinctive parts arranged in rings inside each other which are technically modified leaves: Sepal, petal, stamen & pistil. This flower is referred to as complete (with all four parts) and perfect (with "male" stamens and "female" pistil). The ovary ripens into a fruit and the ovules inside develop into seeds.
