Question

The reason why the fruits of Xanthium are dispersed by animals is that they

• A. Are edible
• B. Have hooks
• C. Are sticky
• D. None of the above

Answer 1

The correct option is B Have hooks

Xanthium has hairy and seeds with hooks that get easily stuck in the fur and hide of animals and get dispersed far off places. They also get dispersed by wind. When climatic conditions are favourable, they burst open by the explosive mechanism and are transported far off places and germinate into new plants. So, fruits of Xanthium are dispersed by animals because, they have hooks and not because, they are edible and sticky.
Therefore, the correct answer is option B.
