$C_3$ plants

Vedclass · Answer

(B) $CO_2$ compensation point is the concentration of $CO_2$ at which the rate of photosynthesis exactly equals the rate of respiration.$C_3$ plants have a higher $CO_2$ compensation point (approximately $25-100 \ ppm$) because they undergo photorespiration,which releases $CO_2$ and reduces the net photosynthetic efficiency.In contrast,$C_4$ plants have a very low $CO_2$ compensation point (approximately $0-10 \ ppm$) because they possess a mechanism to concentrate $CO_2$ around the enzyme $RuBisCO$,effectively suppressing photorespiration.Therefore,$C_3$ plants exhibit a higher $CO_2$ compensation point compared to $C_4$ plants.

Which of the following has a high $CO_2$ compensation point?
