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
