Chlorophyll

Blue to yellow-green pigment (Greek: leaf green) in the leaves of plants that absorbs solar or light energy; see under photosynthesis.

Term (phos = light and sýnthesis = composition) for the process of producing energy-rich biomolecules using light energy. The chloroplasts (organ cells), in which the chlorophyll (leaf green) is located, are responsible for this. Colouring substances such as chlorophyll, carotenoids and flavonoids in leaves or other green parts of plants use solar radiation as an energy source to produce carbohydrate compounds. In the process, carbon dioxide from the air and water are converted into glucose and fructose, while oxygen is released. Plants bind around 150 billion tonnes of carbon dioxide and release 400 billion tonnes of oxygen on earth every year. All the substances necessary for the plant life process are derived from the carbohydrates and nutrients absorbed by the roots.
