He found that in sunlight the plant's leaves made bubbles. And after placing them in darkness they stopped this process. He also explained that only the green parts of the plant actually perform photosynthesis. This experiment led the discovery of the process photosynthesis. During this time he conducted about 500 experiments. The results of his experiments which were published by him are; Experiments upon Vegetables, on the Chemical affects of Plant physiology.
