Answer 1

Answer:

There are five main modes of seed dispersal: gravity, wind, ballistic, water, and by animals. Some plants are serotinous and only disperse their seeds in response to an environmental stimulus. Dispersal involves the letting go or detachment of a diaspore from the main parent plant.

Answer 2

Explanation:

Dispersal of seeds is the spreading of seeds across places. This dispersion of seed can take place by the following means:

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

Wind – some light-weighted seeds tend to float in air and hence are dispersed by wind. Example – Maple

Animal – Seeds that are dispersed by animals have spines which helps them attach to the animal bodies, hence carried to distant places. Example – urena
