WebDispersal of seeds is important for the continued survival of a plant species. The oval-shaped nuts are typically 12-by-10-inches wide. The coconut seed is especially well adapted to increase its range by the method of ocean dispersal.
Some fruits can be carried by water, such as a floating coconut. Schizocarp fruits are in between: they do not open but break into several parts (usually the distinct locules), and each part contains one seed inside.
Experiment with different masses or shapes or sizes of seeds to determine the best shaped seed for wind dispersal. The curation of this content is at the discretion of the author, and not necessarily reflective of the views of Encyclopaedia Britannica or its editorial staff.

Some seeds have little hooks that can stick on to an animal's furry coat.
Derived from a perigynous flower.Pome, 5. Sourced from YouTube. Seeds contained within fruits need to be dispersed far from the mother plant, so they may find favorable and less competitive conditions in which to germinate and grow. Also try dropping a plain "seed" (for example, a regular paper clip with nothing attached) to see what happens.
