Trees are tall plants. They live for many years. Some live for hundreds of years. A tree has three main parts: roots, trunk, and leaves.
Roots grow under the ground. They drink water from the soil. They hold the tree steady. Without roots, trees fall down.
The trunk is the hard middle part. It is like a big straw. It carries water from the roots up to the leaves. The trunk has bark on the outside. Bark protects the tree from bugs and bad weather.
Leaves are green. They catch sunlight. Trees use sunlight to make food. This is a special process. It helps trees grow big and strong. Leaves also clean the air. They take in bad air and give out good oxygen. Humans need oxygen to breathe.
Trees change with the seasons. In spring, new leaves grow. In summer, trees are full and green. In autumn, leaves change color to yellow, orange, or red. Then, they fall to the ground. In winter, many trees sleep. They wait for the sun to come back.
Trees are homes for animals. Birds build nests in branches. Squirrels hide nuts in the trunk. Insects live under the bark. Forests are busy places.
Trees are important for Earth. They give us shade on hot days. They give us wood for houses. They keep the ground healthy. We must protect our trees. They help us live better.
