C4 plant
A C4 plant is a plant that uses C4 carbon fixation pathways in which carbon dioxide is first bound to a phosphoenolpyruvate in the mesophyl cells. This forms a four carbon compound which is later used to produce carbon dioxide to be utilized in a C3 pathway (the calvin cycle and photosynthesis.) C4 plants are better adapted than C3 plants in higher temperatures, intense sunlight, drought, and nitrogen and carbon dioxide limitations. Above is a picture of corn, a C4 plant.
