Assertion is correct,but Reason is incorrect.

Vedclass · Answer

(C) : Tropical plants (mostly $C_4$ plants) are more efficient in $CO_2$ utilization because they have a mechanism to concentrate $CO_2$ around the $RuBisCO$ enzyme,which minimizes photorespiration.$R$: $C_3$ plants do not have a specialized mechanism to minimize oxygenase activity of $RuBisCO$. In $C_3$ plants,$RuBisCO$ often functions as an oxygenase when $CO_2$ levels are low or temperature is high,leading to photorespiration. Therefore,the Reason is incorrect because $C_3$ plants are specifically known for their inability to fully prevent oxygenase activity compared to $C_4$ plants.

$A$: Tropical plants are more efficient in $CO_2$ utilization.
$R$: $C_3$ plants ensure that $RuBisCO$ functions as carboxylase,minimizing oxygenase activity.
