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. |
