Carbon dioxide released by respiration equals the quantity required by photosynthesizing cells. At this moment there is no net gas exchange between the leaves and the atmosphere. This is termed as what?

Explanation

The condition in which the carbon dioxide released during respiration equals the amount of carbon dioxide utilized in photosynthesis is known as the compensation point. At this stage, the rate of photosynthesis exactly balances the rate of respiration, resulting in no net exchange of gases between the leaf and the surrounding atmosphere. In other words, the carbon dioxide produced by respiration is completely used up by photosynthesis, and the oxygen generated during photosynthesis is entirely consumed by respiration. This point represents a state of equilibrium in gas exchange and is often referred to specifically as the CO₂ compensation point.
