Plants adapting to the environment

There are thousands of different plants and they grow in many different places all over the world. Plants grow in hot deserts and under ice and snow. Plants from dry places look very different to plants from wet places. The highest tree ever measured was an Australian eucalyptus. Its highest branch was 132 metres above the ground. There is a plant in Africa that lives in a dry environment. It has a root system more than 100 metres long.

In a tropical rainforest it rains nearly every day. This means that plants can grow quickly. In fact, there are so many plants that low to the ground it is quite dark. So, plants and trees grow higher to find more light. But there's a problem. If a tree has lots of water, it doesn't need a deep root system. If the top of a tree is heavy from the rain, and the root system is shallow, the tree might fall over.

Plants in the tropical rainforest have adapted to these problems. The root systems are wide to provide a good support for the tree. The leaves on some plants have a special cup shape. This helps the rain run off quickly and stops the tree getting heavy with water. Many plants grow very high to get more sunlight. Others have big leaves to help the plants get more light. Some plants grow on tall trees so they are closer to the light.
