C₃ plants are plants in which the initial product of the assimilation of carbon dioxide through photosynthesis is 3-phosphoglycerate, which contains 3 carbon atoms.
Plants that survive solely on C₃ fixation tend to thrive in areas where sunlight intensity is moderate, the temperature is moderate, carbon dioxide concentration is around 200 ppm and groundwater is in plenty.
Wheat is a type of C₃ plant.
