What Are Roots?

What Are Roots? describes how roots help plants survive, using a series of descriptive metaphors. The book describes important structures and functions of a variety of root types. Important ideas include: roots are adaptations that plants have to help them survive, roots take in water and nutrients, roots hold plants in place, and that there are two main types of roots--taproots and fibrous roots. What Are Roots? enables students to learn more about roots than is directly observable. Students use this book to help identify structures on the roots they observe firsthand.
