Summary Introduction

Definition of calyx, corolla, peduncle, receptacle, pedicel, pistil, filament, ovary, and carpel.

Introduction:

A flower at certain times also known as blossom or bloom refers to the reproductive composition found in the flowering plants, also known as angiosperms. The biological role of a flower is to influence the process of reproduction, generally by offering a mechanism for the union of eggs with the sperm.

Explanation of Solution

Calyx refers to the outermost whorl of the flower. It comprises three to five small green colored leaf-like compositions known as sepals. The sepals of a flower in combination are known as calyx. It protects the flower when the flower is present in its bud phase.

The next whorl of the flower that comprises three too many petals is in a combination known as corolla. They work primarily to fascinate pollinators. They are the conspicuous section in various trees. Every flower starts as an embryonic priprimodium. It forms into a bud over the specialized branch at the tip of a stalk known as a peduncle.

In certain cases, when the peduncle exhibits branchlets of small stalks it is known as pedicels. Receptacle refers to the expanded tip of the flower axis or stalk, which contains the floral organs. Stamens are connected with the receptacle around the base of the greenish pistil at the center of the flower. Each stamen comprises slender and semi-rigid filament with a sac.

The upper part of the stigma is associated via a slender stalk-like style to the swollen base known as ovary. The ovaries comprise ovules within them, and such ovules bearing parts are known as carpels.

Conclusion

The calyx, corolla, receptacle, peduncle, pedicel, pistil, filament, ovary, and carpel are the essential parts of a flower. Each of these structure plays an essential role in the process of reproduction.
