Question

Diadelphous condition is found in
A. Pisum
B. Rose
C. Cotton
D. Wheat

Answer 1

Hint: Diadelphous is a condition in which stamen are united by their filaments so as to form two groups. Filaments of nine separate stamens are bound into one unit in this condition, and the tenth posterior stamen remains as a stand portion out of the bundle.

Complete answer: 

> The flower is the plant's reproductive part. It can be categorised by the location or number of the stamens and the petals, the position of the calyx, the androecium and the corolla, and so on. 

> They are called epipetalous when the stamens are attached to the petals. They are classified as epiphyllous when stamens are attached to the perianth. 

> On the basis of stamen fusion, flowers may also be categorised. Stamens remain free in the polyandrous form. In a monadelphous flower, the stamens are joined together into one bundle. 

> The stamens in diadelphous flowers are split into two bundles. If the stamens are joined together into more than two bundles, a flower is said to be polyadelphous. 

> The stamens in pea (Pisum sativum) are 10 or 9 and are diadelphous. The posterior stamen is free and there is a fusion of nine filaments to form a sheath around the ovary. 

> Annual perennial herbs, shrubs and even trees are Solanaceae family species. Many farms, medicinal plants, spices, ornamental plants, etc are part of this family. 

> These are nightshade species, potatoes, chilli peppers, bell and eggplant are examples.

Hence, the correct answer is option (A).

Note: Annual perennial herbs, shrubs and even trees are Solanaceae species. Many farms, medicinal plants, spices, ornamental plants, etc. are part of this family. These are nightshade species, potatoes, chilli peppers, bell and eggplant are some of the examples.
