Question: how has the process of photosynthesis evolved in c4 plants?
Answer: Figure 1. Photosynthesis in C3 and C4 plants. In C4 plants, however, photorespiration is minimized by using compartmentation to ensure that RuBisCO can no longer react with oxygen. ... Carbon is shuttled back and forth between the cells by molecules that contain four carbon atoms, hence the name C4 photosynthesis.
