Photosynthesis and respiration are two central and basic physiological processes in regulation to carbon budget and carbon sink in the terrestrial ecosystem, as well as assessment and feedback of highly variable and fluctuating environmental conditions. Elevated CO2, salinity, alkalinity, drought, flood, nutrient deficiency and toxicity, extreme cold and heat, and various natural and anthropogenic pollutants are critical challenges in near future and their primary target is to alteration of photosynthetic and respirational processes, which ultimately influence the final yield potential of major agricultural crops. However, plants adapt themselves to these environmental circumstances via complicated changes at physiochemical and molecular levels. The current chapter highlights the underline mechanisms of photosynthetic and respiration in response to climate change at physiological, biochemical, and molecular levels. This chapter also covers the timely and substantial information regarding the recent progress in photosynthesis and respiration research. First, an outline of future climate change and its impacts on plant processes, functions, and yield potential is presented. Then, responses and adaptation of photosynthesis and respiration mechanisms against multiple stresses are discussed. Globally the present issues are crucial and this chapter helps in better understanding how plants deal with climatic change and their physiological, cellular, and molecular processes to the development of sustainable environment.
