Ying: Plant using either wind or water for seed dispersal

Plants often depend on wind and water for seed dispersal. Some plant species, such as the Narrowleaf Hawksbeard (Crepis tectorum) and the Common Dandelion (Taraxacum officinale), develop seeds with fluffy appendages that act as parachutes, allowing the seeds to be carried away by the wind over long distances.
