because
1.for avoiding over crowding
2.to eliminate in competitons
3.so that seeds can grow in other places that need plants
4.for the continuation of plants and species life
Yes, seeds can germinate even if they are not dispersed. Seeds can remain dormant until environmental conditions are suitable for germination, such as the right temperature, moisture, and light levels. Dispersal helps seeds find new areas to grow but is not necessary for germination itself.
Ripe fruits of Impatiens when touched burst suddenly. The fruit valves roll inwards and the seeds ejected with great force and get dispersed in all directions.
Seeds of all cultivated plants are dispersed by mammals including human being. Seeds of edible fruits are also dispersed by wild animals, like monkeys and squirrels.
No, in fact some seeds lay dormant for many years and others are triggered by heat (only germinate after a forest fire).

Seeds are dispersed in fruits to help spread them across a large area. Apples, Oranges, and plums all use this ability reduce over population and provide the best change of success for future generations.

Tomato seeds are the obvious example. A visit to a sewage purification works in Summer will show you young tomato plants growing all over.

Seed dispersal is the movement or transport of seeds away from the parent plant. Seeds can be dispersed away from the parent plant individually or collectively, as well as dispersed in both space and time. The patterns of seed dispersal are determined in large part by the dispersal mechanism and this has important implications for the demographic and genetic structure of plant populations, as well as migration patterns and species interactions. There are five main modes of seed dispersal: gravity, wind, ballistic, water and by animals.
