Question : Assertion : The atmospheric concentration of CO_(2) at which photosynthesis just compensates for respiration is referred to as CO_(2) compensation point. Reason : The CO_(2) compensation point is reached when the amount of CO_(2) uptake is less than that generated through respiration because the level of CO_(2) in the atmosphere is more than that equired for achieving CO_(2) compensation point.

1.	Question : Assertion : The atmospheric concentration of CO_(2) at which photosynthesis just compensates for respiration is referred to as CO_(2) compensation point. Reason : The CO_(2) compensation point is reached when the amount of CO_(2) uptake is less than that generated through respiration because the level of CO_(2) in the atmosphere is more than that equired for achieving CO_(2) compensation point.
Answer» If both Assertion & Reason are true and the reason is the correct EXPLANATION of the assertion, then mark a lf both Assertion & Reason are true but the reason is no t the correct explanation of the assertion, then mark b If Assertion is true statement but Reason is false, then mark c If both Assertion and Reason are false STATEMENTS, then mark d. SOLUTION :At very low `CO_(2)` concentration photoynthesis is strongly limited by the low `CO_(2)` while respiratory rates are unaffccted. As a result there is NEGATIVE balance between `CO_(2)` fixed by photosynthesis and `CO_(2)` produced by respiration and a net efflux of `CO_(2)` from the plant By increasing the ATMOSPHERIC concentration of `CO_(2)` at which photosynthesis just compensate for respiration is referred to as `CO_(2)` compensation point.
