Question

Which one bears coma for anemochory?

• A. Cinchona
• B. Calotropis
• C. Alstonia
• D. Both B and C

Answer 1

Answer: (D)

Both B and C

Anemochory for easy dispersal by wind seeds have to be light so that their buoyancy may enable them to float on air over long distances. Certain seeds and a few fruits are provided with appendages which act like parachutes in helping them to float in the air. Coma is a tuft of hair developed as a crown on the seeds of Calotropis, Alstonia (two tufts).

So the correct answer is ' Both B and C'.
