1.	Question : Succelentsare know to keep theirstomata closedduringthe dayto check transpiration . Howdo theymeet theirphotosyntheitcCO_(2) requirements ?
Answer» Solution :Succulentsundergo a specialcarbon pathway called Crassulacean Acid Metabolism(CAM pathway). At nighttime , CAMplantsfor `CO_(2)`with thehelp of Phosphoenol PYRUVICACID ( PEP) and produe Oxalo AceticAcid (OAA) . Subsequently OAAis convertedinto malicacid like `C_(4)`cycleand produces `CO_(2)`. The `CO_(2)`thusformedentersCalvinscycleproduces carbohdrates .
