A) \[{{\text{C}}_{\text{4}}}\text{-}\]pathway
B) \[{{\text{C}}_{\text{2}}}\text{-}\]pathway
C) CAM-pathway
D) \[{{\text{C}}_{3}}\text{-}\]pathway
Correct Answer: C
Solution :
CAM-pathway (Crassulacean Acid Metabolism) is a mechanism of photosynthesis involving double fixation of \[C{{O}_{2}}\] which occurs in succulents belonging to Crassulaceae, cacti, euphorbias and some other plants of dry habitats where the stomata remain closed during the daytime and open only at night. The process of photosynthesis is similar to that of \[{{C}_{4}}-\]plants but instead of spactial separation of initial PEPcase fixation and final rubisco fixation of\[C{{O}_{2}}\], the two steps occur in the same cells but at different times, night and day, eg, Sedum, Kolanchoe, Opuntia, Pineapple, Agave, Vanilla etc.
