Answer:
B. helping the seeds to be scattered in new areas to grow.
Explanation:
- The scattering of seeds away from the parent plant is termed as seed dispersal and there are several mechanisms by which seeds can be dispersed, some of the means include gravity, wind, water, animals, etc.
- Seeds that have spiky structures such as hooks or claws are usually dispersed by animals.
- These spiky structures help the seeds to attach to the animal's fur or a feather and also to the bags or clothes of humans and thus, the seeds get scattered to new places along with the animals as they rub the seeds off their body or they fall on their own.
- Thus, <em>the spiky structure of seeds benefits the plant by as it helps in the dispersal of seeds and the plant can thus, grow in new areas.</em>
