A major limiting factor for photosynthesis in C3 plants is (A) C O2 (B) Temperature (C) Light (D) Water

Tardigrade Admin · Accepted Answer

For C3 plants, C O2 fixation is carried out by enzyme RUBISCO which is highly sensitive to C O2 concentration. Increases in C O2 concentration increases the rate of photosynthesis and decreases in C O2 concentration decreases the rate of photosynthesis.
