The term 'TREE JUICES' can be broken down into two crossword solutions: SAPS (4 letters) and JUICE (5 letters). SAPS stands for 'SAPWOOD, ' which is the outermost layer of wood in a tree. This layer is composed of living cells that transport water and nutrients from the roots to the leaves. JUICE is the liquid extracted from fruits, vegetables, and trees. Tree juices are typically made from the SAPWOOD of trees, such as maple, birch, and walnut. They are often used as a natural sweetener or flavoring in food and beverages.
