Answer 2

The cotton seeds are light weighted and these are covered by thin and light fibers of cotton.

Explanation:

• The dispersal is the process through which the seeds from the plants are spread and carried away through the wind, water and various agents to the distance.
• The fine hair over the seeds helps in reducing the weight of the cotton seeds. These fine hair are blown up by the wind currents and also gives kinetic energy for movements to the seeds.
• The seeds can go upto the long distance to conduct the germination.
