$C_4$ plants

Vedclass · Answer

(B) The $CO_2$ compensation point is the concentration of $CO_2$ at which the rate of photosynthesis exactly equals the rate of respiration.$C_4$ plants are more efficient at photosynthesis than $C_3$ plants because they possess a $CO_2$ concentrating mechanism (Kranz anatomy) that minimizes photorespiration.Due to this mechanism,$C_4$ plants can maintain a positive net photosynthetic rate even at very low concentrations of $CO_2$.Therefore,$C_4$ plants have a lower $CO_2$ compensation point $(0-10 \ ppm)$ compared to $C_3$ plants $(20-100 \ ppm)$.
