An increase in sunlight would lead to the fact that the plant could get burned, as this would lead to rapid evaporation of moisture on its surface and rapid drying. So, the plant, protecting its stem, grows leaves, also providing large areas for absorbing the gases it needs, including carbonate from the air. If we resort to the method of saturating the atmosphere surrounding the plant with various gases necessary for it, then their overdose would lead to the fact that some processes could accelerate or increase their volume for a short time, but others would simply stop, again leading to the death of the plant. For example, if you enrich the surrounding space with carbonate, in order for the plant to produce photosynthesis better, this would lead to the fact that it simply could no longer be in its usual state – absorbing oxygen and releasing this very carbon dioxide, carbonate, which would slow down most processes.
