Is photorespiration present at low light intensity in c3 and c4 plants? Is photorespiration present at high light intensity in c3 and c4 plants?

Expert Answer:

  • Photorespiration only occurs under high light intensities.
  • It also requires high temperatures and high oxygen levels to occur.
  • In C4 plants, the process does not occur.
  • In C3 plants, if the intensity of light is high and O2 levels are high along with high temperature, photorespiration is likely to occur.
