The process which makes a major difference between C 3 and C 4 plants is:

The process which makes a major difference between C3 and C4 plants is:
  1. Glycolysis
  2. Calvin cycle
  3. Photorespiration
  4. Respiration

Solution

Photorespiration is present in C3 plants but absent in C4 plants. C4 plants minimize photorespiration by separating initial CO2 fixation and the Calvin cycle by performing these steps in different cell types. This phenomenon occurs due to the RuBisCO enzyme's dual nature, which works on oxygenase activity if there is less carbon dioxide or more oxygen concentration.
