Assertion: The atmospheric concentration of CO2 at which photosynthesis just compensates for respiration is referred to as CO2 compensation point.
Reason: The CO2 compensation point is reached when the amount of CO2 uptake is less than that generated through respiration because the level of CO2 in the atmosphere is more than that required for achieving CO2 compensation point.
(a) If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.
(b) If both Assertion and Reason are correct but Reason is not a correct explanation of the Assertion.
(c) If the Assertion is correct but Reason is incorrect.
(d) If both the Assertion and Reason are incorrect.
(e) If the Assertion is incorrect but the Reason is correct.
(c) If the Assertion is correct but Reason is incorrect.
Explanation:
Compensation point is that value or point in the light intensity and atmospheric CO2 concentration when the rate of photosynthesis is just equivalent to the rate of respiration in the photosynthetic organ. So that there is not net gaseous exchange.
