Wind Dispersal
Some
seeds are carried to a new place by the wind. These seeds are
very light.
The
seeds of the orchid are almost as fine as dust.
Many
have hairy growths which act like little parachutes and carry
the seeds far away from the parent plant.
The
seeds of the dandelion are carried by the wind.
The
seeds of the thistle are also carried away by the wind.
Both
the dandelion and the thistle have hairy growths at the top of
the seed to carry the seeds far away from the parent plant.
These
seeds are also very light in weight.
Have
you ever heard the saying
"As
light as a thistle down "?
Well
this is where it comes from.
The
fruits of the sycamore have winged seeds and these are also carried
away by the wind.
The
wind causes the ripe fruits of the poppy to sway. This causes
the seeds to fall out. The seeds are very light and are carried
away on the wind.
