Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R).
Assertion (A) : In C₄ plants photorespiration does not occur.
Reason (R) : C₄ plants have a mechanism that increase the concentration of CO₂ at the RuBisCO enzyme’s site i.e. mesophyll cell. This takes place when the C₄ acid is broken down in the mesophyll cells to release CO₂.
In the light of the above statements, choose the most appropriate answer from the option given below:
Assertion Correct
In C4 plants, photorespiration is absent because RuBisCO works in a high carbon dioxide environment.Reason Incorrect
Carbon dioxide concentration increases at RuBisCO site in bundle sheath cells, not mesophyll cells.
C4 acid breaks down in bundle sheath cells, releasing carbon dioxide there
