A student compared young plants of the same species growing on a green roof during a dry period. The plants were exposed to the same conditions.
| Total leaf area (cm²) | Water lost in 6 hours (g) |
|---|---|
| 18 | 0.8 |
| 60 | 2.6 |
Explain how the results support the idea that plants with a smaller leaf area are better able to survive when water is limited.
