Tree roots take up water and some minerals from the soil. How do you think that water gets to the other parts of the tree that need it?

Water mostly enters a tree through the roots by osmosis and any dissolved mineral nutrients will travel with it upward through the inner bark's xylem (using capillary action) and into the leaves. These traveling nutrients then feed the tree through the process of leaf photosynthesis. This is a process that converts light energy, usually from the Sun, into chemical energy that can be later released to fuel an organisms' activities including growth.
