How Seeds Travel
Plants cannot move from place to place, but
seeds can. They can travel 1. .
They may be carried by the 2.
or upon the 3. . They
may also be carried by animals or people.
Seeds that are carried by the wind often have
4. . Maple
(枫树 )
seeds
have wings that spin
(旋转 )
and keep them
in the air for longer, allowing them 5.
in all kinds of places. Depending on
the 6. of the wind, they can
sometimes travel for 7. .
Coconuts
(椰子 )
are carried along by
8. . When a coconut falls
from a tree onto the beach, the 9.
picks it up at high tide
(潮水)
and car鄄
ries it away to grow somewhere else. Its hard
shell
(壳)
allows it to 10.
on the water for a long time. Another way for
seeds to travel is through the digestive
(消化)
systems of animals . Many plants produce
11. that animals like to eat.
The animal receives the nutrients
(营养 )
of
the fruit, but it does not digest the 12.
, which is passed out some time la鄄
ter. Of course, animals move, so the seed can
easily end up a long way away from 13.
, especially if the fruit is eaten by
a bird.
In fact , seeds have a better chance
14. when they are further
away from their parent plant. Growing too
close to the parent plant means seeds might
not get enough sun, water and nutrients from
the 15. . Also, a species is
more likely to 16. if its
members are more 17. .
