Water moves from the soil, through a plant and out of its leaves. This movement of water is called the transpiration stream.
Describe the pathway of water from the soil to the air outside a leaf.
Explain how the loss of water from the leaves causes water to move up the xylem.
A gardener removed all the leaves from a plant.
Explain why the rate of water uptake by the roots of the plant decreased.
