Photorespiration causes a number of impacts on a plant.  Which of these drives the ECOLOGICAL difference between C3 and C4 plants   Question 4 options:   Rubisco mistakes Oxygen for CO2   The plant uses energy to convert the toxic product of photorespiration back into something less harmful   The plant needs a large number of enzymes to be able to regain the energy invested in the 2 carbon molecule produced by photorespiration   None of these explain the difference   The plant needs to do gas exchange to remove oxygen and add CO2 to the cell doing photosynthesis to avoid photorespiration.
