Answer 1

Answer:

Wind dispersal. ... This is wind dispersal. Seeds from plants like dandelions, swan plants and cottonwood trees are light and have feathery bristles and can be carried long distances by the wind. Some plants, like kauri and maple trees, have 'winged' seeds.

Dandelion seeds are dispersed by wind with the help of pappus surrounding the seeds.

Explanation:

Dandelion seeds are attached a lot of feathery bristles called as pappus. These pappus can allow prolonged movement of seeds with the help of air flow to ensure their proper dispersal. During warm and windy conditions seeds can travel within few kilometer distance. Researchers found that seeds contain a kind of stable air bubble known as vortex ring which helps to keep seed remain suspended in air for longer duration. Pappus are able to maintain and stabilize the vortex ring at a fixed distance from seed which help them to be delivered more far distance with wind.
