Roots
There are a variety of types of trees that absorb a lot of water. One of the most popular trees is the weeping willow.
All plants, including trees get their water from the earth through their roots with just a few exceptions.
This process is called transpiration.
Through a series of capillary bodies that we so commonly call, roots.
Aspen trees roots will grow to where the water is.
Osmosis through the roots, then capillary action up the trunk and branches.
The roots of trees
Deciduous trees are trees that lose their leaves. Trees that don't lose their leaves are "Evergreens". Evergreen trees have needles, instead of flat leaves, to survive winter hardship. Needles cut evaporation so trees can save water - dear in the winter. Not all trees that bear needles are evergreen, for example the larch drops it's needles in the Autumn.
Not really. The roots take in water, which passes up through the plant, carrying nourishment as it goes. Any excess water leaves through the leaves! On the other hand, if the roots are exposed and are still white, (as opposed to the dark brown barked roots that trees often have) they can loose lots of water. It's best to keep them covered.
Fir, spruce, hemlock, and other coniferous trees all have thick, waxy needles that prevent water from evaporating
