Describe the various ways by which seeds are dispersed.

Following are the ways in which the seeds are dispersed:

1) Dispersal by wind- The seeds that are usually smaller in size or that have wings or hair like structures get dispersed by wind to far away places. Examples- sunflower, drumstick, maple, etc.

2) Dispersal by water- Fruits or seeds that develop floating ability in the form of spongy or fibrous coat are carried away by water to different places. Example- coconut.

3) Dispersal by bursting- Seeds get dispersed by the bursting of fruits with sudden jerks. Examples- balsam, castor, etc.

4) Dispersal by animals and birds- Spiny seeds get attached to the body of animals and birds and are carried to new sites by them. Some fruits have hooks that cling to the fur or clothes. Examples- mango, xanthium, etc.
