Question

The saturation point of CO2 in C4 plants is

Answer 1

For C4 plants, the light saturation point is higher and the light compensation point is lower than for C3 plants. Both of these characteristics relate to the ability of C4 plants possess to increase the amount of CO2 available to the Calvin-Bensoncycle.

Answer 2

Answer:

The carbon dioxide compensation point is high in C3 cycle (about 50 ppm). The carbon dioxide compensation point is low in C4 cycle (2 to 5 or even 0 ppm). In high light intensity, the rate of CO2 evolution is high in C3 plants. In the high light intensity, the rate of CO2 evolution is very low in C4 plants.
