I: | Water stress can cause the stomata to close, hence, reducing the carbon dioxide availability. |
II: | Water stress also makes leaves wilt, thus, reducing the surface area of the leaves and their metabolic activity as well. |

Statement I: | Green house crops such as tomatoes and bell pepper are allowed to grow in carbon dioxide enriched atmosphere. This leads to higher yields. |
Statement II: | C3 plants respond to higher carbon dioxide concentration by showing increased rates of photosynthesis, leading to higher productivity. |
1. | Both Statement I and Statement II are correct and Statement II explains Statement I |
2. | Both Statement I and Statement II are correct but Statement II does not explain Statement I |
3. | Statement I is correct but Statement II is incorrect |
4. | Statement I is incorrect but Statement II is correct |
Statement I: | Despite the presence of a green leaf, optimal light and carbon dioxide conditions, the plant may not photosynthesize if the temperature is very low. |
Statement II: | If a chemical process is affected by more than one factor, then its rate will be determined by the factor which is nearest to its minimal value. |
