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

How many carbon atoms does the primary carbon dioxide acceptor have in C₃  photosynthesis?

How many ATP and NADPH are respectively required to make one molecule of glucose through the Calvin pathway?

Identify the incorrect statement regarding the comparison of ${\mathrm{C}}_4$ plants to the ${\mathrm{C}}_3$ plants:
1. They tolerate higher temperatures
2. They show a response to high light intensities
3. They have a lower productivity of biomass
4. They lack photorespiration

The bundle sheath cells are characterized by:

The primary ${\mathrm{CO}}_2$ acceptor in ${\mathrm{C}}_4$ plants is:
1. RuBP in mesophyll cells
2. RuBP in bundle sheath cells
3. PEP in mesophyll cells
4. PEP in bundle sheath cells

The ${\mathrm{C}}_3$ pathway:
1. is common to all plants
2. takes place in mesophyll cells in ${\mathrm{C}}_4$ plants
3. takes place in bundle sheath cells in ${\mathrm{C}}_3$ plants
4. does not take place in CAM plants

In ${\mathrm{C}}_4$ pathway, the 4-carbon compound transported to bundle sheath cells most commonly is:

The most common enzyme in the world is:

The 2-carbon compound formed in photorespiration is:
