how can you prove that plants absorb water through xylem

Transpiration is the loss of water from a plant in the form of water vapor. Water is
absorbed by roots from the soil and transported as a liquid to the leaves via xylem. In the
leaves, small pores allow water to escape as a vapor. Of all the water absorbed by plants,
less than 5% remains in the plant for growth. This lesson will explain why plants lose so
much water, the path water takes through plants, how plants might control for too much
water loss to avoid stress conditions, and how the environment plays a role in water loss
from plants.
Objectives:
At the completion of the lesson, students will be able to:
1. Define transpiration and explain why it occurs in plants.
2. Follow the pathway that water takes through plants from root uptake to
evaporation at leaf cell surfaces.
3. Describe how the driving force for water movement and any resistances to its
flow through the plant are the two major components controlling rates of
transpiration.
4. Describe how environmental conditions alter rates of transpiration.
5. Explain how the plant is able to alter rates of transpiration.
INTRODUCTION
Welcome to a lesson that will examine how water moves through plants. Plants lose
gallons of water every day through the process of transpiration, the evaporation of water
from plants primarily through pores in their leaves. Up to 99% of the water absorbed by
roots is lost via transpiration through plant leaves. How and why do they do it? How do
the plants avoid losing too much water? What environmental conditions control water
loss? The animation in the lesson will provide a visual tool for you to understand these
processes as well. The animation contains the text below
