C4 photosynthesis is one of three metabolic pathways found in the photosynthetic tissues of vascular plants for assimilation of atmospheric carbon dioxide (CO2). Like crassulacean acid metabolism (CAM) photosynthesis, C4 photosynthesis has evolved from the ancestral C3 pathway. C4 photosynthesis is an adaptation that enhances CO2 assimilation in wa...
