NEETBotanyPhotosynthesis in Higher Plants
Read the following statements and choose the following option: 1. The C3 and C4 plants respond differently to CO2 concentrations 2. C4 plants show saturation at about 360 µlL-1 while C3 responds to increased CO2 concentration and saturation is seen only beyond 450 µlL-1 3. The stroma lamellae membranes lack PS I as well as NADP reductase enzyme. 4. The cyclic flow results in the synthesis of ATP, and NADPH + H+.
Options
- AOnly 2 is correct
- BOnly 4 is correct
- CBoth 1 and 2 are correct
- DBoth 2 and 3 are correct
Correct answer
C. Both 1 and 2 are correct
Step-by-step solution
The C3 and C4 plants respond differently to CO2 concentrations. At low light conditions neither group responds to high CO2 conditions. At high light intensities, both C3 and C4 plants show increase in the rates of photosynthesis.
