Q. No.| Assertion(A): | Cyclic electron flow is the only photosynthetic mode of generating ATP for bundle sheath cells. |
| Reason(R): | Bundle sheath cells contain PS I but no PS II. |
| 1. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 2. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
| 3. | (A) is true but (R) is false. |
| 4. | Both (A) and (R) are false. |
Subtopic: C4 Cycle (Hatch & Slack Pathway) |

Level 3: 35%-60%
Both and CAM pathways are regarded as compromises. The reason for this would be:
| 1. | Both pathways lead to reduction of photosynthesis to enable water conservation. |
| 2. | To maintain high photosynthetic levels C4 compromises on water loss and CAM compromises on loss of carbon. |
| 3. | Both minimize photorespiration and optimize the Calvin cycle. |
| 4. | To maintain high photosynthetic levels CAM compromises on water loss and C4 compromises on loss of carbon. |
