Chlorophyll molecule contains _____________________
The process of capturing light energy from the sun is dependant on magnesium. Magnesium is bound in the central atom of the porphyrin ring of the green plant pigment chlorophyll. Magnesium is the element that causes plants to be able to convert light into energy. Chlorophyll is identical to haemoglobin except for the fact that the magnesium atom at the center has been taken out and replaced with iron. The whole basis of life and the food chain is seen in the sunlight-chlorophyll-magnesium chain. Since animals and humans obtain their food supply by eating plants, magnesium can be said to be the source of life.
