A scientist investigated the effect of carbon dioxide concentration on the rate of photosynthesis in greenhouse tomato plants (Solanum lycopersicum).
Table 1 shows the rate of photosynthesis, measured as the mass of glucose produced per square metre of leaf area per hour, at different carbon dioxide concentrations.
| Carbon dioxide concentration (ppm) | Rate of photosynthesis (g m−2 h−1\text{g}\ \text{m}^{-2}\ \text{h}^{-1}g m−2 h−1) |
|---|---|
| 150 | 1.2 |
| 300 | 2.5 |
| 600 | 5.1 |
| 900 | 7.2 |
| 1200 | 8.4 |
| 1500 | 8.4 |
Use information from Table 1 to describe the effect of carbon dioxide concentration on the rate of photosynthesis.
