How do C 4 plants minimize photorespiration?

C 4 plants have separate cells for light reactions and carbon reactions, which means that oxygen and rubisco do not come into contact, minimizing photorespiration. The other options are incorrect as they involve storing oxygen or carbon dioxide in malate, which is not a mechanism used by these plants.

Multiple Choice

How do C₄ plants minimize photorespiration?

A) Stomata are only opened at night, storing oxygen in malate. During the day the oxygen is released for photosynthesis.
B) The light reactions and carbon reactions occur in different cells, so carbon dioxide does not come into contact with rubisco.
