compensation point

compensation point defined in 1951 year

compensation point - compensation point;
compensation point - In darkness green plants respire, taking up oxygen and giving off carbon dioxide. In weak light photosynthesis begins as well, removing carbon dioxide and releasing oxygen. With increase in light intensity rate of photosynthesis increases until a point, the compensation point, is reached at which rates of photosynthesis and respiration are equal and there is neither absorption nor evolution of either carbon dioxide or oxygen. With further increase in light intensity carbon dioxide is absorbed and oxygen is given off. The compensation point has also been defined in terms of carbon dioxide concentration. The CO2 compensation point is the concentration of carbon dioxide in the surrounding atmosphere at which rates of carbon dioxide intake and evolution in photosynthesis and respiration respectively, are equal. It differs in different plant species.
