(b) Fuchsia is an inferior flower, which has the ovary beneath other flower parts. The androecium has stamens with anthers that contain the microsporangia. The stamens produce fine, dustlike grains, called pollen, and the carpels produce ovules. A … The ovary encloses the ovules, or potential seeds. The female part of a flower, consisting of a stalk with an ovary at the base and a stigma, which traps pollen, at the tip.
