Vedclass · Answer

(B) $C_4$ plants are photosynthetically more efficient than $C_3$ plants because they possess a specialized leaf anatomy known as Kranz anatomy,which includes two types of chloroplasts: bundle sheath chloroplasts and mesophyll chloroplasts.These plants operate a dicarboxylic acid cycle (Hatch-Slack pathway) in addition to the Calvin cycle.The primary $CO_2$ acceptor molecule,phosphoenolpyruvate $(PEP)$,is present in mesophyll cells and has a very high affinity for $CO_2$,even at low concentrations.This mechanism effectively minimizes photorespiration,as the $CO_2$ concentration around the enzyme $RuBisCO$ is kept high,making them more efficient.
