How are coconut seeds dispersed?
In coconut, the seeds are dispersed by water as the seeds have spongy or fibrous outer coat which float on water.
Which seed is dispersed by animals?
The seed of these plants gets attached on the fur of animals with the help of these hooks and are carried away to different places, far from their parent plants. Examples of plants having seeds dispersed by animals are Dates, rambutan, sea grapes, sea holly, tamarind, raspberry, sunflower, tomatoes.
What are the 10 types of seed dispersal?

How are palm trees dispersed?
The seeds of palm trees can also be dispersed by water. If they grow near oceans, the seeds can be transported by ocean currents over long distances, allowing the seeds to be dispersed as far as other continents.
What plants are spread by water?
Dispersal of Seeds by Water. Brooklime. Yellow Water Lily. Mangrove. Although seeds of plants that grow in water are obviously spread by water, there are many other ways in which water plays a part in dispersing seeds. Plants which grow beside water often rely on water to transport their seeds for them. They may produce light seeds which float, ...
What trees can colonize the middle of a stream?
They may produce light seeds which float, or there may be fluff that helps buoyancy.
