Vedclass · Answer

(D) $C_4$ plants are evolutionarily adapted to high-temperature and high-light environments.$1$. Productivity: Due to the absence of photorespiration,$C_4$ plants show higher biomass production and productivity compared to $C_3$ plants.$2$. Water Use Efficiency: $C_4$ plants are more efficient in water usage. They fix the same amount of $CO_2$ while losing only about half the water that $C_3$ plants lose through transpiration.$3$. Rubisco Efficiency: In $C_4$ plants,the $CO_2$ concentration mechanism (Kranz anatomy) ensures that the concentration of $CO_2$ around the enzyme Rubisco is high,which minimizes the oxygenase activity of Rubisco and maximizes its carboxylase activity,making it more efficient than in $C_3$ plants.Therefore,all the given statements are correct.

Select the correct option regarding $C_4$ plants compared to $C_3$ plants.
