What is Photosynthesis?

Photosynthesis is the conversion of sunlight energy, carbon dioxide and water into sugar and starch. Compounds such as chlorophyll, which give plants their green colour, are centres for photosynthesis. Such compounds accelerate a reaction which can occur naturally, as shown here, if the carbon dioxide (left) and water (right) are moving quickly relative to one another. Arrows show the direction of travel. [NS] {NR}
