The term 'polyadelphous' is related to -
- gynoecium
- androecium
- corolla
- calyx
The Correct Option is B
Solution and Explanation
The correct answer is:
Option 2: Androecium
Explanation:
The term "polyadelphous" refers to the condition in which the stamens (male reproductive organs) of a flower are united into more than two bundles. This term is used to describe the arrangement of stamens in the androecium of a flower.
In more detail:
Monadelphous: All stamens are united into a single bundle.
Diadelphous: Stamens are united into two bundles.
Polyadelphous: Stamens are united into more than two bundles.
Since this term specifically refers to the arrangement of stamens, it is related to the androecium (the male reproductive part of the flower).
Why Other Options Are Incorrect:
Option 1: Gynoecium – This refers to the female reproductive part of the flower (carpels), not the arrangement of stamens.
Option 3: Corolla – Refers to the petals of a flower, not the stamen arrangement.
Option 4: Calyx – Refers to the sepals, the outermost whorl of the flower, which is not related to stamen arrangement.
Thus, polyadelphous is related to the androecium.

Concepts Used:
Flower
A flower is a modified shoot. A flower bud is formed when shoot apical meristem in angiospermous plants gets transformed into floral meristem and leaves transform into floral appendages.
In angiosperms, flowers are the reproductive units and they are meant for sexual reproduction. A typical flower possesses four types of floral organs or whorls — sepals (calyx) , petals (corolla), stamens (androecium), and carpels (gynoecium). These whorls are arranged on the swollen end of the stalk or pedicel, called the thalamus or receptacle.
Importance of Flowers:
Flowers are the place where pollination takes place. Due to the vibrant color and fragrance of flowers, insects get attracted to them that helps in the process of pollination that in turn leads to seed production. These seeds turn into fruits and are also a very important part of plant survival as they create new plants.
