At a plant's light compensation point the rate of photosynthesis is greater than the rate of respiration.

​

Light Compensation Point

The light intensity level at which the rate of photosynthesis equals the rate of respiration, leading to no net gain of energy by the plant.

Photosynthesis

The process by which green plants and some other organisms use sunlight to synthesize foods with carbon dioxide and water, producing oxygen as a byproduct.

Respiration

(1) Cellular respiration is the process by which cells generate ATP through a series of redox reactions. In aerobic cellular respiration, the terminal electron acceptor is molecular oxygen; in anaerobic cellular respiration, the terminal acceptor is an inorganic molecule other than oxygen. (2) Organismic respiration is the process of gas exchange between a complex animal and its environment, generally through a specialized respiratory surface, such as a lung or gill.
