Chapter 38, Problem 1IQ

Identify the flower parts in the following diagram.

Summary Introduction

To identify: The flower parts in the given diagram.

Introduction: Flowers refer to reproductive structures of flowering plants. The flowering plants are also termed angiosperms. Angiosperms are defined as vascular plants. They possess stems, roots, and leaves and also they are capable of producing flowers. Flowers of angiosperms exhibit stamens, carpels, pollen grains, and so on. Angiosperms bear seed in a flower.

Explanation of Solution

Pictorial representation: The flower parts are labeled in Fig.1.

Fig.1: Parts of the flower

Stamen: In a flower, stamen is a male reproductive organ. It comprises two parts, namely anther and stalk.

Anther: It is the part of the stamen that produces the pollen, male gametophyte.

Filament: It is a long, slender structure that supports an anther.

Carpel: It is a female reproductive organ that is present in flowers. It is made up of stigma, style, and ovary.

Stigma: The top part of the pistil (female reproductive part) is known as stigma, and it is usually sticky in nature.

Style: It is a long and slender neck-like projection from the ovary. It acts as a passageway for the pollen that moves from the stigma to the ovary.

Ovary: It is the basal portion of the pistil (female reproductive organ), which contains ovules.

Sepal: It is the outer part of the flower that appears often in green and leaf like and encloses the developing bud. 

Receptacle: It is the thickened portion of a stem from which floral organs grow.

Ovule: It comprises egg cells that grow into a seed when it is fertilized. 

Petal: It is the colored portion of a flower, and it is termed as modified leaves. It surrounds the reproductive parts of the flower.
