Question

During self pollination of Mirabilis,

• A. Flowers are closed
• B. Flowers are open and growing style brings the stigma in contact with anthers
• C. Filaments bring anthers in contact with stigma
• D. Style bends to bring stigma in contact with anthers

Answer 1

The correct option is C Filaments bring anthers in contact with stigma

Mirabilis has homogamous flowers. Homogamous flowers are the bisexual flowers in which anthers and stigma mature at the same time. Thus, self pollination occurs in Mirabilis. When the anthers and stigma mature, the filaments of anther recoil to bring them in contact with the stigma and as the anthers dehisce, pollen grains are deposited on the surface of the stigma. Thus, self pollination occurs in this way.

So, the correct answer is C.
