The sepals are the green-leaf like structures that enclose and protect the developing flower. It is a modified leaf in the outermost whorl calyx of a flower.

The calyx (which the sepals are the outer part of) protects the bud before it opens. The sepal allows the calyx to open and provides rigid support for the petals and reproductive organs of the flower.

A flower may have one or more simple pistils more simple pistils.

The stigma is often sticky or hairy, to retain the pollen.

A flower may have one or more pistils which consist of a basal portion called the ovarywhich contains the embryo seeds or ovules and area where the pollen is received called thestigma. Often the stigma may be borne on a stalk-like structure called the style. The pistil consists of ovule-bearing basic units called carpels.
