Verified Answer
In the following question, a statement of Assertion(A) is given follow...
C3 plants exclusively fix CO2 via the Calvin Benson pathway. The leaf cells of C4 plants possess two types of chloroplast, bundle sheath cells and mesophyll cells. The mesophyll cells of C4 plants mesophyll cells. The mesophyll cells of C4 plants carboxylase, which catalyses the fixation of CO2 with PEP to form oxaloacetic acid. The bundle sheath cells exhibit high RuBP carboxylase and the other enzymes of the Calvin-Benson cycle. C4 plants are highly productive photosynthetically in view of the low affinity of RuBP carboxylase for its substrate. But CO2 is concentrated as C4 acids due to the activity of the PEP carboxylase, which in effect maintains high pool levels of CO2. C4 plants are related to very high light-harvesting saturation points. C4 plants exhibit low rates of photorespiration only in bundle sheath cells. C4 plants are adapted to high temperature. C4 plants show better utilization of available water but it cannot be the cause of its higher productivity.
