A student used a potometer to measure the rate of transpiration from a leafy shoot under four different environmental conditions. The results are shown in the table.
| Condition | Transpiration rate (arbitrary units) |
|---|---|
| A: Still air, low light | 2 |
| B: Still air, high light | 8 |
| C: Windy, high light | 15 |
| D: Windy, high light, high humidity | 5 |
Describe how the environmental factors affect the rate of transpiration and describe the mechanism by which water is transported from the roots to the leaves in the xylem.
