Question

Hygroscopic hair for fruit dispersal to moist areas occurs in

• A. Sonchus
• B. Cotton
• C. Mucuna gigantea
• D. Entada gigas

Answer 1

The correct option is A Sonchus

Dispersion means the process of distribution of seeds and fruits to different wider areas for the production of the new plant. In many plants like, Sonchus, the calyx is persistent and modified into hairy structures, the Pappus, which is present on top of the fruit. The pappus acts as a parachute and helps the air current to carry the fruits. The pappus in some fruits is hygroscopic and helps the fruit in settling down.

So the correct answer is 'Sonchus'.
