NEET Biology question
The given table shows the CO2 compensation point and optimum CO2 concentration for photosynthesis in C3 and C4 plants.
| Parameter | C3 plants | C4 plants | |---|---|---| | CO2 compensation point | 25-100 ppm | A | | Optimum CO2 concentration | 450 ppm | B |
Select the correct values for A and B.
Answer: (B)
Solution
C4 plants, owing to their highly efficient PEP-carboxylase-based CO2-concentrating mechanism, have a much
