There are 4 different of seed dispersal and they are:

Some seeds are carried to a new place by the wind.

Some plants have pods that explode when ripe and shoot out the seeds.

The animal eats the fruit but only the juicy part is digested. It also hooks on the animal.

A bean seed is a Dicot. • Seed coat• The bean seed has a split going down the middle of
the seed.• The two large parts of the seeds are called cotyledons. Cotyledons supply food for the young plant as its
growing.

Monocots are seeds that only have 1 cotyledon, such as the corn seed, The corn seed has a seed coat but it does not slip off as easily as the bean seed does.
It stays in one piece.
