The process by which organisms with chlorophyll, such as algae, some bacteria and green plants convert energy from sunlight into chemical compounds called photosynthesis. This basic process of nature synthesize organic substances from other inorganic. It comprises two phases. In the first of which light is absorbed by chlorophyll. This green pigment converts solar energy into chemical energy through a series of reactions. The speed of this phase increases with light intensity. In the second stage, which can be done in the dark, the stored energy is used to reduce water and carbon dioxide into organic carbon and release oxygen, the rate of this reaction increases with temperature. Photosynthesis allows carbon dioxide in the atmosphere is transformed into organic compounds in living things, while oxygen release, which is essential for life on the planet.
Elements that are important in this process are water and carbon dioxide, because the reaction that produces some of them.
The leaves of plants are a perfect laboratory in which the solar light energy is transformed
