TRANSPORT IN PLANTS

Plants get water and minerals from the soil and prepare their own food in the leaves. See the arrows going upward in the picture below. These arrows show Xylem tissue which transports water and minerals to all parts of the tree. The arrows going downward show the Phloem tissue which carries food from the leaves to all parts of the tree. The innermost brown portion is heartwood which gives mechanical support to the tree. 

Some trees have been reported to be as high as 125 meters, and sometimes more. Do you know the highest tree in the world is a Redwood tree in California, US? Its name is Hyperion. Imagine how tough it is for these trees to send water and minerals from roots to the top.
