In the chloroplast:
| Statement I: | The membrane system is the site of enzymatic reactions leading to synthesis of sugar. |
| Statement II: | The stroma is responsible for trapping the light energy and also for the synthesis of ATP and NADPH. |
| 1. | Both Statement I and Statement II are correct |
| 2. | Both Statement I and Statement II are incorrect |
| 3. | Statement I is correct but Statement II is incorrect |
| 4. | Statement I is incorrect but Statement II is correct |

NCERT textbook mentions that “immediately after light becomes unavailable, the biosynthetic process continues for some time and then stops”. Why does it stop after some time?
| 1. | The respiration stops in the absence of light and hence synthesis of sugars stops |
| 2. | The reactions of the biosynthetic phase are directly dependent on light |
| 3. | The reactions of the biosynthetic phase are dependent on the products of light reaction |
| 4. | This is a mistake in NCERT as Dark Reactions will continue throughout night |
