    Theodor Wilhelm Engelmann was a German microbiologist whose 1882 experiment measured the effects of different colors of light on photosynthetic activity and showed that the conversion of light energy to chemical energy took place in the chloroplast. In 1881, he observed the movement of bacteria towards...

    The key cellular process identified with energy production is photosynthesis. In the process of photosynthesis, plants use the energy of sunlight to convert water and carbon dioxide into high-energy carbohydrates—sugars and starches—and oxygen, a waste product. The investigations of many scientists have...
