Compensation point means

Given table shows the CO_(2) compensation point and optimum CO_(2) concentration for photosynthesis for C_(3) and C_(4) plants. |(ul(" " C_(3) " Plants" " " C_(4)" Plants")),(ul(underset("point")(CO_(2)" compensation")" "25-100 "ppm" " "A " ")),(ul(underset("cocentration")("Optimum " Co_(2)) " " "B 360 ppm"))| Select the correct values for A and B.

The C_(4) plants are photosynthesis more efficient then C_(3) plant because (a) The CO_(2) efflux is not prevented (b) They have more chloroplasts (c) The CO_(2) compensation point is more. (d) CO_(2) generated during photorespiration is trapped and recycled through PEP carboxylase

The following is not relate to C_4 plant Water use efficiency is more Photorespiration is not detectable CO_2 compensation points is high The primary acceptor of CO_2 is a 3C compound

Assertion. The atmospheric concentration of CO_(2) at which photosynthesis just compensates for respiration 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.

Define light compensation point.

At CO_(2) compensation point, photosynthesis is

CO_(2) concentrating steps are found in

High CO_(2) concentration in leaf interior will cause

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
