Expert Solution
Step 1

The compensation point for light is the level of illumination at which there is precisely no net production of oxygen. At this stage, the rate of oxygen production by photosynthesis and the amount of oxygen used by the plant as a result of cellular respiration are equal. However, there are some expenses associated with increased photosynthetic capacity in sun plants. As compared to shade plants, sun plants often have higher rates of leaf respiration, which raises the light-compensation point. Because shade leaves have a thinner coating of mesophyll cells and more chloroplasts, they are better able to capture sunlight at low radiation levels.The compensation point for light is the level of illumination at which there is precisely no net production of oxygen.
