Trees are big plants. They live on land. We see trees every day. They are in parks, gardens, and forests. Some trees are very tall. Some trees are small. Trees are beautiful and help our world.
Trees have three main parts. These parts are the roots, the trunk, and the leaves. The roots are under the ground. You cannot see them. The roots hold the tree in the soil. They take water and food from the dirt. The trunk is the big, strong part in the middle. It is made of wood. It has brown bark on the outside. The branches grow out from the trunk. The leaves grow on the branches. Most leaves are green.
There are two main types of trees. Some trees have leaves all year. They are always green. Other trees lose their leaves when it gets cold.
Trees are very important for the Earth. They help us breathe. Trees take in dirty air. They make clean air. This clean air is called oxygen. People and animals need oxygen to live. Without trees, we cannot live. They are the lungs of our planet.
Trees are also homes for many animals. Birds build their nests in the branches. They sing songs in the morning. Squirrels live in holes in the trunk. They look for food. Many small bugs and insects live on the bark. Trees keep these animals safe from rain and sun.
We get many things from trees. We get food. Many fruits grow on trees. Apples, oranges, bananas, and mangoes come from trees. Some trees give us nuts. We also use wood from trees. We use wood to make paper, books, pencils, tables, and chairs. Some houses are made of wood.
Trees change during the year. We call these times seasons. In spring, trees grow new green leaves and beautiful flowers. In summer, the leaves are big and dark green. They give us cool shade when the sun is hot. In autumn, the leaves change color. They turn yellow, orange, and red. Then, the leaves fall to the ground. In winter, many trees have no leaves. They look like they are sleeping.
Trees make our world beautiful. They keep our air clean. They give us food and wood. We must take care of trees. We can plant new trees in our gardens. We must not cut down too many trees.
