Explain `CO_(2)` compensation point.

At CO_2 compensation point

Compensation point is

Assertion. The atmospheric concentration of CO_(2) at which photosynthesis just compensates for resoiration is referred to as CO_(2) compensation point. Reason. CO_(2) -compensation point is reached when the amount of CO_(2) uptake is less than that generated through respiration because the level of CO_(2) is more than that required for achieving CO_(2) -compensation point.

Which of the following photosynthetic characteristics are present in C_(3) plants but not in C_(4) plants- I. CO_(2) compensation point of 0-10 ppm- II. Relatively higher rate of photorespiratory CO_(2) evolution- III. Presence of well developed bundle sheath- IV. Initial involvement of RUBP carboxylase in CO_(2) assimilation - Select the correct answer using the codes given below

Compensation point means

Which one of the following have high CO_(2) compensation point :
