Question

What is compensation point ?​

Answer 1

The (light) compensation point is the light intensity on the light curve where the rate of photosynthesis exactly matches the rate of cellular respiration. ... For instance, in the early morning and late evenings, the compensation point may be reached as photosynthetic activity decreases and respiration increases.

The Compensation Point is the point at which Photosynthesis and Respiration are in balance, so (in a perfect world) the amount of oxygen being produced by photosynthesis will just balance the amount being used by respiration. At this point there will be NO oxygen bubbles being produced in the leaf discs.

Answer 2

➜ When the rate of photosynthesis is equal to rate of respiration, it is called as compensation point.

• The rate of liberation of O2 during photosynthesis is equal to the rate of liberation of CO2 during respiration.
• Thus, there is no net uptake of gases from the environment.
• Compensation point is usually reached at dusk and down and on a cloudy day.
