The photosynthesis of carbohydrates by the chloroplasts of green plants is an important process, and one that has received considerable study. Most of these studies have been concerned with the effect of external factors, such as light, temperature, and carbon dioxide concentration on the rate of photosynthesis by the plant. These studies have yielded valuable information, but the actual mechanism of photosynthesis is yet unknown; a new line of attack is necessary before the chemioal changes involved in the photosynthesis of carbohydrates by the whole plant can be elucidated because these changes are complicated by other processes, such as respiration, which are going on at the same time; furthermore, there are many substances present which do not play a direct part in the process.
