Without plants there could be no life on earth. Most of the food we eat comes from plants.  

The green part of most plants is one of the most important things in nature.  It is called chlorophyll, a name that means light green leaf.

Roots are important to plants in many ways. They absorb liquids, store food, hold plants erect and absorb water from the air.

Trunk reaches up into the air and branches are arranged to expose the greatest possible area to the sun.

Leaves are most commonly the greenest part of a flowering plant. Their most common job is that of exposing green tissue to the sun, too.
