Wind, being carried by birds or animals, on moving water, some shatter & throw their seeds quite far.

What plant are we talking about? There are a number of adaptations to spread seed.

Things like fleshy fruits are eaten by birds or animals. Some have hooked fruits (eg, grass grains) that are caught in fur.

Others have fruits which burst open to expel the seed (lupins)

Others have fine seed born by wind, eg. the fluffy seeds on a dandylion.

Some, like Weeping willows, have seed transported by running water.

Some (like callistemons) hold their seed until it is removed or the plant is burned.

So you can see there are many different conditions required.
