A structure can help a seed move away from its parent plant. Wings can slow falling in moving air, hooks can attach to fur, and buoyant coverings can help floating. These are clues, not guarantees of a particular journey.

Worked example

A hooked burr can cling to fur. The hooks support a possible transport method; they do not prove where this seed traveled.

Would you believe it?

Water vapor is invisible. The visible white mist above warm water is made of tiny liquid droplets, not individual visible gas particles.

Question 2 A seed case catches on a coat because it has hooks. What does that structure help? attachment to a passing carrier photosynthesis in the coat making water

Question 3 A seed floats in a stream without sinking immediately. What route is possible? transport by sound only movement using legs water transport

Question 4 A bird carries a fruit containing seeds to another place. What route is shown? seed-made rockets animal transport magnetic transport
