A tree is the biggest plant that grows. Trees can live for a very long time, and they are alive all year long, even when they look dead in winter. In this newly illustrated book, you will learn how a tree grows and how it gets food and water. You can also find out what happens to water after it travels through a tree's roots, branches, and leaves, and how to figure out a tree's age. Clyde Robert Bulla's simple and concise text and Stacey Schuett's lush illustrations follow a tree's continuous life cycle through spring, summer, winter, and fall.
