Question

Which one of the following bear winged fruits?

• A. Oroxylon
• B. Dioscorea
• C. Moringa
• D. Cinchona

Answer 1

The correct option is B Dioscorea

Dioscorea is a genus of flowering plants in the family Dioscoreaceae, the seeds of this family are called as samara or winged seeds.
A samara is a winged achene, a type of fruit in which a flattened wing of fibrous, papery tissue develops from the ovary wall. A samara is a simple dry fruit and indehiscent. The shape of a samara enables the wind to carry the seed farther away than regular seeds from the parent tree. The seed can be in the centre of the wing or the seed can be on one side, with the wing extending to the other side, making the seed autorotate as it falls.
Thus, the correct answer is option B.
