Vedclass · Answer

(A) $C_{4}$ plants are more advantageous than $C_{3}$ plants because they can efficiently fix carbon even in low $CO_{2}$ concentrations.In hot and dry conditions,plants close their stomata to prevent water loss,which leads to a decrease in internal $CO_{2}$ levels.$C_{3}$ plants suffer from photorespiration under these conditions because $RuBisCO$ acts as an oxygenase,leading to the loss of $RuBP$ and inhibition of the Calvin cycle.$C_{4}$ plants possess a specialized anatomy called $Kranz$ anatomy and a $PEP$ carboxylase enzyme that has a high affinity for $CO_{2}$,allowing them to maintain photosynthesis even when $CO_{2}$ levels are low.
