WebMay 14, 2024 · C 4 Plants. Over 8,000 species of angiosperms have developed adaptations which minimize the losses to photorespiration. They all use a supplementary method of … WebC4 photosynthesis produces 4-carbon compounds as the initial product of photosynthesis. C4 photosynthesis occurs in two different parts of a leaf to avoid photorespiration. CO2 fixation occurs in mesophyll cells using PEP carboxylase, insensitive to O2. Since there is little or no Rubisco in the mesophyll of C4 plants, there is no photorespiration.
