Question

Fruit dispersal in Asteraceae is usually by

• A. Mechanical means
• B. Wind
• C. Water
• D. Animals

Answer 1

Answer: (A)

Mechanical means

In Asteraceae, the fruit is cypsela which is a dry single-seeded fruit formed from a double ovary of which the only one develops into a seed. In cypsela, the pericarp is free from the testa. It develops from an inferior bicarpellary ovary. The fruit dispersal in Asteraceae occurs by mechanical means.

So, the correct answer is 'Mechanical means'.
