Answer 2

Answer:

There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals.

Explanation:

Water – it takes place in aquatic plants and plants growing near water bodies, here seeds are dispersed through water. These seeds tend to develop a fibrous or spongy coating. Example – coconut
