WebC4 plants Definition: C4 plants are a type of plant that uses the C4 carbon fixation pathway. In this pathway, the C4 cycle occurs with CO2 present bound to phosphoenolpyruvate in the mesophyll cell. This results in the formation of a four-carbon compound called oxaloacetate. 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 CO 2 uptake which forms a 4-carbon molecule instead of the two 3-carbon molecules of the Calvin cycle. Hence these plants are called C 4 plants.
