A researcher measures the volume of water that evaporates from the leaves of two young plants of the same species over one hour. Both plants are growing in the same moist soil.
| Plant | Volume of water evaporated in one hour in cm³ |
|---|---|
| A | 2.1 |
| B | 3.6 |
Predict which plant takes up water from the soil faster.
Use the data to explain your prediction.
