I: | The C4 acid OAA is formed in the mesophyll cells. |
II: | Malic acid or aspartic acid are transported to the bundle sheath cells. |
III: | C4 acids are broken down to release carbon dioxide and a 3 carbon molecule in mesophyll cells. |
IV: | The 3 carbon molecule is transported back to the bundle sheath cell where it is converted to PEP again. |
I: | there is no synthesis of sugars |
II: | there is release of carbon dioxide with the utilization of ATP |
III: | ATP is synthesized but NADPH is not synthesized |
Statement I: | In C4 plants, photorespiration does not occur. |
Statement II: | C4 plants do not have RuBisCO in any of their cells. |

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. |

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. |
