This tutorial examines how water moves through a plant. Follow the pathway that water takes through plants from the roots to evaporation from cells in the leaves. Learn what controls rates of transpiration, how environmental conditions alter rates of transpiration, and how the plant itself can change rates of transpiration. Includes a glossary and a detailed animation.
