Vedclass · Answer

(C) In $CAM$ (Crassulacean Acid Metabolism) plants,stomata open at night to take in $CO_2$,which is fixed into organic acids like malic acid. This process is known as dark acidification.During the day,these organic acids are decarboxylated to release $CO_2$ for the Calvin cycle.Therefore,the Assertion is correct,but the Reason is incorrect because decarboxylation occurs during the day,not at night.

$A$: Dark acidification occurs in $CAM$ plants.
$R$: Organic acids are decarboxylated during night.
