Trees are the biggest plants of all. There are three kinds of trees – palm, evergreen and deciduous trees. The trunk of a tree is covered with bark. You can tell the age of a tree by counting the rings on a tree stump. Some trees can live for 4,000 years!

 

 

 

 

 

 

 

Some trees keep their leaves all year. They are evergreen.

Most pine and fir trees are evergreen. They have cones and are called conifers. Cones are the flowers of the conifer tree. The leaves on conifers are called needles. A few needles drop off every day and new ones grow all year round.

 

 

 

 

Some trees lose all their leaves in autumn.

In autumn, the weather becomes colder and there are fewer hours of sunshine. This makes the leaves of some trees change colour and fall off. Trees that lose all their leaves after they turn brown in the autumn are called deciduous trees. Oak and beech trees are deciduous.

 

 

 

 

Roots grow down to find water.

A tree’s roots can spread wider under the ground than the branches spread above the ground.
