Plants cannot move from place to place, but seeds can. They can travel great distances. They may be carried by the wind or upon the water. They may also be carried by animals or people. Seeds     1     (carry) by the wind often have special shapes. Maple seeds have wings that spin and keep them in the air for longer, allowing them to land in all kinds of places.     2     (depend) on the strength of the wind, they can sometimes travel for hundreds of kilometres.

Coconuts are carried along by ocean     3     (current). When a coconut falls from a tree onto the beach, the sea picks     4     up at high tide and carries it away to grow somewhere else. Its hard shell allows it to float on the water for    5     long time. Another way for seeds to travel is through the digestive systems of animals. Many plants produce     6     (attract) fruits that animals like to eat. The animal receives the nutrients of the fruit,     7     it does not digest the seed, which is passed out some time     8     (late). Of course, animals move, so the seed can easily end     9     a long way away from the parent plant, especially if the fruit     10     (eat) by a bird.
