Comparing such a plot for C3 and C4 plants reveals differences between the two pathways of carbon metabolism, which of the following given statements will be incorrect?

#Unit 6. System Physiology – Plant
  1. In C4 plants, photosynthetic rates saturate at ci values of about 100–200 ppm, reflecting the effective CO2- concentrating mechanisms operating in these plants
  2. In C3 plants, increasing ci levels continue to stimulate photosynthesis over a much shorter CO2 range than for C4 plants
  3. In C4 plants, the CO2 compensation point is zero or nearly zero,  reflecting their very low levels of photorespiration

  4. In C3 plants, the CO2 compensation point is about 50–100 ppm at 25°C, reflecting CO2 production because of photorespiration
