Heya...
Here is your answer ----
The different means of seed dispersal are as follows --
• Dispersal by water : Seeds of plants that grow in or near water are carried by water to different places. For example, Coconut.
• Dispersal by Wind : Seeds such as that of the milkweed are extremely light and have hairs. They are blown away by Wind to faraway places. Example - Sycamore.
• Dispersal by explosion : In some plants such as the lady's finger, the dried fruit explodes spreading the seeds away from the mother plant.
• Dispersal by animals : Many plants have seeds with spines and hooks. Such seeds stick to the feathers of animals and birds and hair of animals and are ultimately dispersed to faraway places.

Heya!
A plant produces a large number of seeds, if all these will fall below the plant and start growing, they will not get enough space, water, Minerals and the sunlight and they will not develop into healthy plants. Many of them even die. Nature has arranged some agents of dispersal by which the seeds of a plant get scattered over a large area. This is called dispersal of seeds.
Here are some means of dispersal of seeds -
• Dispersal by wind - seeds of cotton or Dandelion have tiny hairs surrounding them. While the Maple seed has wings attached to it. these adaptations help the seeds to be carried out by wind.
• Dispersal by water - the coconut seed has a thick coat of fibre that enables it to float in water, the Lotus fruit has a spongy part that enables it to float. these plants grow near water and their seeds are carried to far off places by water.
• Dispersal of seeds by animals - Some seeds such as xanthium and tiger nail have hooks or spines which help them to stick to the fur of animals or to our clothes with the fruit pass out unharmed in the waste and germinate where they fall.
• Dispersal by explosion of fruit - the fruit of geranium, blasam and pea burst on drying. This causes the seeds to be thrown away from the parent plant.
Hope it helps! :D
