Question

The fruits of Plumbago are dispersed by animals because they have

• A. Edible pulp
• B. Spiny surface
• C. Sticky surface
• D. Falling on muddy banks

Answer 1

The correct option is C Sticky surface

Fruits and seeds are provided with appendages or sticky secre­tions which facilitate their mechanical dispersal by animals. Some fruits as those of Boerhaavia repen, Cleome viscosa, etc possess sticky glands so that they stick to the faces and bodies of grazing animals and are thereby dispersed. Many seeds, as those of Aegle marmelos, Plumbago, mistletoe, etc are sticky and are thereby benefited.

So the correct answer is 'Sticky surface'.
