Dispersal of Seed

​

Seeds need to travel in order to survive.

Seeds cannot travel on their own. They need help from other things in the environment.

DISPERSAL OF SEEDS CHART

INVENTION OF VELCRO

This happened in 1948. One day George Mestral came back from a walk with his dog. He was amazed to find seeds sticking all over his clothes and on his dog’s fur.

He wondered what made them stick. So he observed these seeds under a microscope. He saw that the seeds had many tiny hooks which got stuck to clothes or fur. This gave Mestral the idea of making Velcro. He made a material with similar tiny hooks that would stick. Velcro is used to stick together many things – clothes, shoes, bags, belts and many more. What a way to take inspiration from nature!
