In plants, the style is the long, slender stalk that connects the stigma to the ovary. It’s the place where female reproductive cells are made and contained, and it is what eventually develops into a seed after fertilization, only for the seed to then ripen and produce a complete adult plant.

A flower, sometimes known as a bloom or blossom, is the reproductive structure found in flowering plants (plants of the division Magnoliophyta, also called angiosperms). The style is extremely important during the fertilization process, because this is not only the location where the pollen tube forms but also the checkpoint that stops incompatible pollen from penetrating the ovary. Moreover, the pillar-like stalk through which the pollen tubes grow to the ovary is the style. Basically, each flower consists of a floral axis upon which are borne the essential organs of reproduction (stamens and pistils) and usually accessory organs (sepals and petals); the latter may serve to both attract pollinating insects and protect the essential organs.
