• A. Only statement 1 is correct.
• B. Only statement 2 is correct.
• C. Both the statements are correct.
• D. Both the statements are incorrect.

Answer 1

The correct option is C Both the statements are correct.

• Some plants produce seeds that are covered in hooks or spines. These seeds get attached to animals fur or feathers. They are carried upto a certain distance away from their parent plant.
• Later, these seeds may either fall off, or are rubbed off by the animals. In this way the seeds are dispersed to a new surrounding where they germinate. E.g., Xanthium and Urena.
• Some seeds (e.g. balsam) grow in capsules which when touched, burst opens and scatters the seeds all around.
